The SparkFun Power Delivery Board uses the STMicroelectronics STUSB4500 controller to negotiate USB Power Delivery (PD) contracts with compatible chargers and adapters. Instead of being limited to 5 V from a standard USB connection, this board can request higher voltages — typically 5–20 V and up to 100 W — from any USB-C PD power source.
The STUSB4500 handles all power negotiation autonomously using profiles stored in its built-in non-volatile memory. Configuration is done over I²C, and the Qwiic connectors make it easy to connect to a microcontroller for setup. Once configured, the board operates standalone — no microcontroller needed during normal use.
Key Features
- USB-C Power Delivery – Negotiate 5–20 V from PD-compatible adapters
- Up to 100 W – High-power output from a single USB-C connection
- STUSB4500 Controller – Autonomous PD negotiation with NVM-stored profiles
- Qwiic / I²C Interface – Solderless configuration via Qwiic connector
- Standalone Operation – No microcontroller required after initial configuration
- Through-Hole Breakout – SDA and SCL plated through-holes for non-Qwiic setups

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
- USB Power Delivery (PD)
- USB Power Delivery is a USB-C charging standard that lets a power supply and device negotiate higher voltages and power levels. If a board requires PD input, you need a compatible USB-C PD power adapter and cable, not just any USB-C charger.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
