From the project
Standalone USB-C Power Delivery trigger board (5V-20V / 3A+) using STUSB4500 & KiCad
A compact, standalone USB Power Delivery (PD) sink trigger board based on the STUSB4500 controller[cite: 1, 4]. Automatically negotiates high-voltage profiles (up to 20V @ 3A+) using internal NVM in Auto-Run mode, eliminating the need for an external MCU during standard operation[cite: 1].
