Ch32-Ant: Ch32V003 RISC-V board with Stemma QT

What is it?

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)
• USB support
• Arduino compatible
• Schematics is available.

Warning

V1.0.0 has G pin near the 5V unconnected
