CH32L103 PD Development Board

Overview

Based on CH32L103, PD development board.
[Commercial use prohibited]
1. The Type-C

project itself uses the CH32L103 development board, which includes a key and LED for operation.
The step-down uses an LDO, outputting 100mA
compatible with WCH's CH32L103 protocol (IO needs modification). Later, it may be modified based on the PD protocol provided by WCH to induce 5V, 9V, 12V, 15V, and 20V respectively when a button is pressed.

2. Project progress
[2024.09.17]

[V1 version] Added software example, inducing 5V, 9V, 12V, 15V, and 20V respectively when a button is pressed sequentially. Simultaneously, the LED serves as an indicator for the correct orientation of CC1 and CC2; the LED lights up when CC2 is pressed.
Modified based on the WCH official website example program
