This is a small, breadboard-compatible development board for the CH32V003F4U6 MCU with a Stemma QT connector.
Why did you make it?
It was created, because I needed a cheap development board with a Stemma QT connector. The CH32V003 seemed like the perfect MCU for the task. It's Arduino-compatible, supports USB (pure software USB), and is cost-effective.
What makes it special?
Stemma QT connector.
Pin-to-Pin compatible with Esp32-C6-Bug.
Logic voltage can be switched using on-board 0 ohm resistor(3.3V or 5V)
