Overview
The M5Stack Cardputer Adv (Advanced) is a card-sized programmable development platform powered by the ESP32-S3FN8 processor on a Stamp-S3A module, featuring 8MB PSRAM and 8MB Flash. It packs a 1.14-inch color TFT display, a full 56-key QWERTY keyboard, advanced audio capabilities (ES8311 codec, MEMS mic, 1W speaker, 3.5mm headphone jack), a BMI270 6-axis IMU, IR emitter, microSD expansion, and a 1750mAh battery. With HY2.0-4P Grove and EXT 2.54-14P expansion ports, magnetic base, and LEGO-compatible mounting, it is designed for embedded prototyping, smart home systems, industrial automation, and custom IoT applications. Programmable via Arduino, UiFlow2, ESP-IDF, and PlatformIO.
