5A maximum output
Three configurable profiles
I2C configuration support
The SparkFun Power Delivery Board is the most flexible development-oriented option in this guide, carrying a 4.3 rating and a design centered on configurable USB power delivery. Unlike a simple trigger module that requests one preset voltage, this board lets a connected controller select among three power delivery profiles through I2C. It combines a USB-C sink interface with integrated monitoring and switching functions.
Pros
- Highly programmable profiles
- Supports up to 20V
- Qwiic connection simplifies control
- Integrated voltage monitoring
- Certified USB PD controller
Cons
- Requires additional Qwiic wiring

Its 5V to 20V input and output range gives it more headroom than many fixed 5V boards, while the listed 5A output ceiling makes it relevant to embedded systems, test equipment, and maker projects that need negotiated power. The STUSB4500 controller handles negotiation and is certified for USB Type-C revision 1.2 and USB Power Delivery revision 2.0. Integrated VBUS monitoring and PMOS switch gate drivers add useful control at the hardware level.
The main trade-off is complexity. Unlike a DIP-switch board, it expects a host system to communicate over I2C, so users need to understand profiles and wiring. The supplied information also notes that wires and Qwiic wires are not included. That limitation is reasonable for developers but less convenient for someone seeking an immediate USB-C-to-DC conversion.
This is the recommendation for builders who want active control over negotiated power rather than a fixed trigger. Choose it when firmware, selectable profiles, and integration with an embedded controller matter more than a simple enclosure-ready module. It is the strongest all-around choice for a programmable power delivery board.
Three Programmable Delivery Profiles
Programmable profiles make the board more adaptable than a fixed-output trigger. A host controller can request a suitable power configuration and coordinate the behavior of the connected load rather than relying on one hard-coded voltage.
Monitoring and Switching Integration
Integrated VBUS voltage monitoring and switch gate drivers reduce the amount of supporting circuitry a project needs. This is particularly useful when the board is being incorporated into a more sophisticated power-management design.

It supports PD 2.0, PD 3.0, QC, FCP, and AFC, allowing it to request 5V, 9V, 12V, 15V, or 20V from a compatible charger. That broad compatibility is valuable for makers working with more than one class of USB-C supply.
Pros
- Five boards included
- Broad fast-charge protocol support
- Compact housed module format
- Supports 20V output
- Suitable for legacy conversions
Cons
- Lowest listed product rating
- Voltage selection details are unclear
We may earn a commission when you buy through this link, at no additional cost to you.
The listed maximum capability is 20V at 5A, or 100W, although actual output remains constrained by the attached power supply and load. Each module is only 21.5 by 11.5 by 4.2 millimeters and weighs 4 grams, making the housed format practical for project boxes and cable adapters. The package includes five units, which is useful when prototyping multiple voltage requirements or converting several legacy devices.
Its main drawback is that the supplied listing does not explain the adjustment method as clearly as products that use a DIP switch or a dedicated diagram. Buyers should verify the module's output configuration before attaching it to sensitive electronics. The lower 3.9 rating also suggests less uniform buyer satisfaction than the leading products in the guide.
Despite that limitation, the multi-pack format and broad protocol support make this a useful budget choice for experimentation. It is best suited to makers who already understand fixed-voltage conversion and want several compact modules rather than one programmable development platform.
One Charger, Several Legacy Devices
By negotiating a supported voltage from a USB-C charger, the module can replace a traditional DC supply for compatible electronics. This makes it useful for consolidating the number of power adapters needed for a collection of projects.
A Practical Five-Pack
Five units provide enough inventory for multiple builds or spare boards. The compact housed construction also makes each module easier to integrate than a completely exposed bare board.

It negotiates with USB-C PD and BC1.2 sources, supports PD 3.0 and PD 2.0, and offers selectable output from 5V through 20V. A DIP switch gives users visible manual control over the requested voltage.
Pros
- Clear DIP switch adjustment
- Strong 4.5 buyer rating
- Supports 100W output
- Over-voltage and thermal protection
- Reversible USB-C insertion
Cons
- Requires manual voltage configuration
- Output still depends on charger support
We may earn a commission when you buy through this link, at no additional cost to you.
The module can support up to 100W when the source and load permit, which makes it useful for testing devices, converting fixed-voltage equipment, and creating compact USB-C-powered adapters. Reversible USB-C insertion reduces the chance that a cable will be connected incorrectly. Listed protection against excessive temperature and voltage improves confidence during bench use.
Manual configuration is the main compromise. A user must understand the DIP switch pattern and verify that the charger offers the desired PD profile. The board does not remove the need to check compatibility; it simply provides a convenient way to request a supported fixed voltage.
For most people seeking an affordable trigger board, this is a particularly balanced pick. It is easier to understand than a firmware-controlled board, more transparent than modules with unclear voltage selection, and comes in a two-board pack for parallel projects or a spare.
Hardware-Controlled Voltage Selection
A DIP switch is a practical middle ground between a completely fixed board and firmware-configurable hardware. It allows the requested voltage to be changed without writing code, although the correct switch positions must be confirmed before connection.
Protection for Testing Work
The listed over-temperature and over-voltage protections make the decoy board more appropriate for evaluating charging behavior. Protection does not replace correct wiring or source compatibility checks, but it adds a useful safeguard during testing.

We may earn a commission when you buy through this link, at no additional cost to you.
Its standout feature is the combination of automatic and manual control. A long press of the PowerON control can shut down a running Raspberry Pi 5, while automatic startup can return the computer to operation when power is restored. The default Always-ON behavior is disabled, and manual activation is required for ordinary startup, according to the supplied product information.
This narrow purpose is also the main limitation. It is not a universal board for negotiating 5V, 9V, 12V, 15V, or 20V outputs for laptops, routers, or other devices. Buyers looking for a general power conversion module should choose a trigger board instead. The value here comes from dependable power behavior within a specific computer ecosystem.
For Raspberry Pi 5 owners who need clean startup and shutdown behavior, this is the premium platform-specific pick. It solves a real operational problem rather than simply offering another way to request a USB-C voltage.
Clean Recovery After Power Loss
Automatic startup lets a Raspberry Pi 5 resume operation after its supply returns, reducing the need for physical intervention. That is valuable in remote installations where a user may not be physically present.
Manual Control Without Normal Operation
A long press of the PowerON switch provides a way to request shutdown while the computer is running. It supplements the automatic behavior and makes local control more convenient.

- Voltage selection method unclear
We may earn a commission when you buy through this link, at no additional cost to you.
Its maximum stated output is 20V at 5A, or 100W, when paired with an appropriate charger and load. The supplied specifications appropriately note that actual performance depends on both. At approximately 23 by 11.5 by 4 millimeters, each bare board is small enough for embedded installations, while its solder pads provide direct integration access.
That bare format is the principal trade-off. Users need to solder connections, identify the appropriate voltage selection method, and verify polarity before connecting a load. It is more suitable for experienced makers and integrated products than for a quick, tool-free adapter.
Choose this board when broad charger compatibility and a five-board inventory are priorities. It is particularly compelling for users who need to support several common USB charging standards rather than only PD and QC.
One Trigger for Multiple Standards
Protocol breadth improves the chance that a USB-C adapter already owned by the user can supply the required voltage. This is useful in mixed environments where chargers may implement different fast-charging standards.
Direct Integration Into Projects
The exposed pads allow the module to become part of a custom adapter or enclosure. That flexibility comes with the expectation that the builder will handle wiring and verify output settings.

We may earn a commission when you buy through this link, at no additional cost to you.
The board can support up to 100W, or 20V at 5A, subject to the capabilities of the charger and load. Reversible USB-C insertion adds convenience, while the listed over-voltage and over-temperature protection improves safety during testing. The four included modules make it practical for several devices or ongoing prototyping.
The product still requires users to confirm the DIP switch combination against the board's diagram and verify the output with a multimeter before attaching equipment. Screw terminals are convenient for bench prototypes, but they may not suit a very thin or unusually shaped enclosure. The fixed terminal design is also less flexible than direct soldering.
For users who want the convenience of screw terminals without giving up adjustable voltage output, this is a strong selection. It is especially appealing for repair work, laptop power experiments, LED-strip testing, and general electronics development where wiring may need to change repeatedly.
Solder-Free Project Workflow
Screw terminals make it possible to change a load connection without rebuilding the circuit. This reduces setup time and makes the board particularly useful for iterative testing.
Five Practical Voltage Levels
The DIP switch covers the common 5V, 9V, 12V, 15V, and 20V output levels used by many USB-C-powered devices. Checking the diagram and measuring the result remains important before applying power to the load.

Buying Guide – How to Choose the Best Power Delivery Board
The right power delivery board depends on the device being powered, the available source, the required voltage, and the amount of configuration you want. Protocol support and electrical protections matter, but installation method and platform compatibility often determine whether a board is practical.
Determine the Required Voltage
Start with the voltage printed on the power input of the device you intend to connect. USB-C does not guarantee one universal operating voltage, so a board capable of negotiating 5V is not automatically suitable for equipment expecting 12V, 15V, or 20V. Select a model that exposes the required output clearly, and confirm whether voltage selection is automatic, controlled by a DIP switch, or configured through firmware.
Prioritize a model that can request the exact level required by your load. A broader range provides more flexibility, but the important criterion is whether the desired voltage is available and easy to select.
Check Current and Total Power
Voltage alone does not determine whether a board can power a device. Current capacity and total wattage also matter, particularly for laptops, storage arrays, and other demanding equipment. A board claiming 20V at 5A can theoretically deliver 100W, but only when the charger, cable, board, and load all support that combination. Lower-current USB-C sources may negotiate a reduced profile even on a board with a higher maximum.
Compare the source and load together. Treat the board's maximum rating as a ceiling rather than a guaranteed result, and select a source that can supply the voltage and current your equipment expects.
Match Supported Charging Protocols
USB Power Delivery is only part of the negotiation picture. Some trigger boards also support QC, QC4+, BC1.2, PPS, FCP, AFC, and other standards. Broad protocol support can make an existing charger more useful, especially when working with a mixed collection of USB-C power supplies. If every source you own implements USB PD, a PD-focused board may be sufficient.
Review the protocol list alongside the output levels you need. More protocols increase compatibility, but they do not guarantee that a charger will provide the exact current or voltage required by a particular device.
Choose the Right Configuration Style
Fixed trigger modules require little configuration, while DIP-switch boards provide simple manual selection. Screw terminals or solder pads determine how the output connects, and a Qwiic or I2C board supports more sophisticated software-controlled profiles. Programmable boards suit embedded developers, but they also require a host controller, correct wiring, and confidence in the configuration process.
Choose the simplest control method that meets your needs. Use a preconfigured board for a single project, and reserve programmable power delivery for systems that genuinely benefit from selectable profiles.
Evaluate Protection and Monitoring
Over-voltage and over-temperature protection add valuable safeguards, especially when testing unfamiliar chargers or loads. Integrated VBUS monitoring is even more useful because it gives a host system a way to observe the negotiated bus voltage. Protection features are not substitutes for correct wiring, but they help limit the consequences of an unsuitable configuration.
Prioritize boards with clearly stated protection, and confirm the polarity and output using a meter before attaching expensive equipment. For repeated bench work, visible monitoring and recovery behavior are more important than a long list of unsupported features.
Account for Form Factor and Wiring
Compact bare boards fit embedded projects and custom enclosures, while housed modules are easier to handle and often more convenient for cable adapters. Screw terminals speed up temporary connections but occupy more space than soldered wires. A Raspberry Pi expansion board may have a suitable shape and interface for its intended platform, yet offer little value as a general trigger module.
Measure the available enclosure space and consider whether the board will be handled frequently. Choose the connection style that matches the installation rather than the one that seems fastest in a demonstration.
Distinguish Boards from Motherboards
A full motherboard's power-delivery system powers its processor, memory, storage, and expansion devices from standard ATX connectors. A USB-C trigger board instead negotiates a source voltage and exposes that power to a smaller external device. These categories solve different problems, even though both involve the language of power delivery.
Choose a trigger or expansion board for embedded power conversion and a motherboard for a complete desktop computer. Comparing their maximum wattage figures without considering their intended loads can lead to an unsuitable purchase.
Consider the Complete Platform
For a desktop platform, processor support, memory generation, expansion slots, storage layout, networking, firmware features, and BIOS compatibility all influence the final result. A robust VRM is important, but an attractive board is only useful if it supports the chosen CPU and intended accessories. For AM5 boards, confirm whether a BIOS update is required for newer processor families.
Build a checklist from the complete system rather than focusing on one headline specification. The motherboard's power design should support the processor, while connectivity and storage should match the way the computer will actually be used.
How to Use and Care for Your Power Delivery Board
Begin by identifying the device's required input voltage, current, and connector arrangement. Inspect the USB-C charger and cable to determine which PD or fast-charging profiles they offer, then choose a compatible trigger profile. Connect the board to the source before attaching the load, and use a multimeter to confirm the negotiated output whenever the wiring or switch configuration changes.
Observe polarity carefully and keep the board within its specified voltage and current limits. Do not assume that every USB-C charger supports 20V or 5A; a board may request a lower profile when connected to a limited source. For exposed trigger boards, inspect solder joints, provide strain relief for wires, avoid pinching the cable, and keep the assembly away from moisture, conductive debris, and heat sources.
For programmable boards, configure the desired power profile through the host controller and confirm the behavior before enabling a sensitive load. For Raspberry Pi power boards, use the stated startup and shutdown controls as intended rather than assuming they behave like a standard ATX switch. Motherboards should be installed with the correct socket, memory, cooling, firmware, and power connections, with the manufacturer's instructions followed for updates and initial configuration.

What is a USB-C power delivery trigger board?
A power delivery trigger board negotiates with a USB-C charger and requests a specific voltage for a connected device. It is often used to replace a barrel-plug supply with USB-C input. The output is still limited by the charger, cable, board, and load, so a board advertised at 100W does not guarantee 100W in every setup.
Can every USB-C charger provide 20V and 5A?
No. USB-C describes a connector and a broad set of capabilities, not one universal power level. A charger may provide only 5V, may support a different PD profile, or may lack the required current. Check the charger specifications and use a board with clearly exposed voltage selection to request an appropriate level.
Are trigger boards and USB-C power adapters the same?
A trigger board is the active module that performs negotiation and exposes a fixed DC output, while a finished USB-C power adapter combines that function with a connector, cable, and enclosure. Trigger boards are preferred for embedded projects because their output pads or terminals can be integrated directly into a custom design.
How do I choose between a DIP switch and I2C control?
A DIP switch is faster for manual testing because voltage profiles can be changed without firmware or a host controller. I2C or Qwiic control is better for embedded systems that need programmable profiles, status monitoring, or coordinated behavior. Choose the simpler method unless the project genuinely needs software-managed power.
Is 100W enough to power a laptop?
It can be, but only if the laptop accepts USB-C input and the charger, cable, trigger board, and laptop all support the required power level. Some laptops negotiate specific profiles, require more current than other devices, or use proprietary behavior that a generic trigger board cannot satisfy.
Do I need a multimeter when using a trigger board?
A multimeter is strongly recommended, especially when testing a new voltage setting or an unfamiliar charger. It confirms the actual output and helps identify incorrect switch positions, wiring mistakes, or an incompatible power source before the load is connected.
Can a Raspberry Pi 5 power expansion board replace a general trigger board?
Usually not. A Raspberry Pi 5 expansion board is designed around that computer's startup, restoration, and shutdown behavior. A general trigger board is more appropriate when a laptop, router, modem, or other fixed-voltage device needs to request power directly from a USB-C adapter.
What should I check before buying a high-end AM5 motherboard?
Confirm processor support, required BIOS updates, memory type, PCIe and M.2 layout, case compatibility, networking needs, and the available power connectors. A strong VRM is important for high-end CPUs, but the board should also fit the complete system and support the accessories you plan to install.
Final Thoughts on Choosing the Best Power Delivery Board
The SparkFun USB-C Qwiic board is the leading recommendation for programmable projects because it combines three configurable profiles, a 5V-to-20V range, 5A output, and I2C control. The USB-C PD/QC Decoy Board is the strongest value choice for straightforward fixed-voltage work, while the GeeekPi Raspberry Pi 5 board is the premium pick for platform-specific automatic startup and manual shutdown.
For a simple conversion, prioritize the exact voltage your equipment needs, source compatibility, and a connection method you can use safely. A DIP-switch module is often ideal for bench testing, whereas I2C control makes sense when firmware must coordinate power. Full ATX motherboards belong in a different category and should be selected around processor support, VRM strength, expansion, storage, and connectivity.
Current prices, availability, and charger compatibility can change, so check the latest listing and technical documentation before ordering. Verify the output with a suitable meter, follow the board's wiring diagram, and avoid treating a maximum wattage claim as a guaranteed result without checking every component in the power path.
