FlappyBoard is a minimum development board for the CH32V203G6 microcontroller. The goal is simplicity, convenience and low-cost.
It’s simple and convenient to use USB download of WCHISPTool. Also serial download and debug port download is available.
WCHISTool requires correct MCU model (CH32V203) to download. The DIP switch shall be ON for downloading, and power the board with BOOT0 button pushed. If everything goes well, WCHISPTool shall report the MCU.
There are two LEDs on the board, including PWR for power status (3.3V powered) and PB8 for user-defined LED.
There are two buttons on the board, including NRST for system reset and BOOT0 for boot mode (the default is to run user program in Flash, and push button to run bootloader in ROM).
See more on GitHub. It’s under a CERN Open Hardware license version 2 – permissive.
