QT Py CH32V203 Dev Board with STEMMA QT / Qwiic

This diminutive dev board features the powerful CH32V203 low-cost processor that's all the trend: based on RISC-V and cheaper than an 8-bit core! This little one is a great way to get started in the CH32x processor family, with everything you need to build many USB-based projects at an excellent price.

The CH32V203G6 has a single 32-bit RISC-V core, running up to 144MHz, with 1-cycle multiply/divide. Inside is 10KB SRAM, 32KB single-cycle Flash as well as an additional 'external XIP' 224KB of Flash that can be used for program or data storage but is not as fast as the 32KB. There's also extras you expect: ADC, timers, USB device, UART, I2C and SPI.
