The Power Delivery Board uses a standalone controller to negotiate with the power adapters and switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output; it can deliver the board as part of SparkFun’s Qwiic connect system, so you won’t have to do any soldering to figure out how things are oriented.
The SparkFun Power Delivery Board takes advantage of the power delivery standard using a standalone controller from STMicroelectronics, the STUSB4500. The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algorithm to negotiate a power delivery contract with a source (i.e. a power delivery wall wart or power adapter) without the need for an external microcontroller. However, you will need a microcontroller to configure the board. PDO profiles are configured in an integrated non-volatile memory. The controller does all the heavy lifting of power negotiation and provides an easy way to configure over I²C.
To configure the board, you will need an I²C bus. The Qwiic system makes it easy to connect the Power Delivery board to a microcontroller. Depending on your application, you can also connect to the I²C bus via the plated through SDA and SCL holes.

Learn KiCad with Peter Dalmaris
The Academy Pro Box "Design PCBs like a Pro" offers a complete, structured training programme in PCB design, combining online learning with practical application. Based on Peter Dalmaris’ KiCad course, the 15-week programme integrates video lessons, printed materials (2 books), and hands-on projects to ensure participants not only understand the theory but also develop the skills to apply it in practice.
Unlike standard courses, the Academy Pro Box provides a guided learning path with weekly milestones and physical components to design, test, and produce working PCBs. This approach supports a deeper learning experience and better knowledge retention.
The box is ideal for engineers, students, and professionals who want to develop practical PCB design expertise using open-source tools. With the added option to have their final project manufactured, participants complete the programme with real results – ready for use, testing, or further development.
