(SPIDER Automation) Adafruit QT Py CH32V203 Dev Board | 32-bit RISC-V MCU with STEMMA QT
Description
The (SPIDER Automation) Adafruit QT Py CH32V203 Dev Board is a pocket-sized, highly capable microcontroller board that brings the open-standard 32-bit RISC-V architecture to Adafruit’s popular QT Py form factor. Driven by the CH32V203 microcontroller, this tiny board packs a powerful punch, operating at clock speeds up to 144 MHz while maintaining a remarkably small physical footprint.
Equipped with an integrated STEMMA QT connector, the board lets you easily connect a wide array of plug-and-play I2C sensors, displays, and actuators without needing a breadboard or soldering iron. It features 10KB of SRAM and a flexible memory layout comprising 32KB of ultra-fast single-cycle internal flash alongside an additional 224KB of external XIP flash for expanded program and data storage.
