A new guide in the Adafruit Learning System today: Phyx LANA TNY CH32V203
The LANA TNY board is Phyx‘s take on an Adafruit QT Py and Seeed studio XIAO bite-sized development boards but with added SMD pins for optional extra IO capabilities and a built-in WS2811 compatible LED output. The LANA TNY is a small development board based around the WCH CH32V203 RISC-V microcontroller.
The CH32V203G6 has a single 32-bit RISC-V core, running up to 144MHz, with 1-cycle multiply, and hardware 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 it is not as fast as the 32KB. There are also extras you expect: ADC, timers, USB device, UART, I2C and SPI.
