Adafruit QT Py CH32V203 Dev Board
          The CH32V203G6 has a single 32-bit RISC-V core, running up to 144MHz, with 10KB SRAM and 32KB single-cycle Flash. There's also extras you expect: ADC, timers, USB device, UART, I2C and SPI. It definitely does not run CircuitPython or Micropython, and Arduino support is very early. It's definitely not good for beginners!
