From the project
Personal electronics and PCB projects created in KiCad with full documentation.
A compact, configurable USB-C Power Delivery trigger module based on the CH221K, designed for safe and reliable voltage PD negotiation with a simple and robust power output.
The output is directly driven by the negotiated voltage from the CH221K, ensuring consistent and reliable operation across all supported voltage levels.
An RGB LED is used to indicate power state:
