Product Description

The AtomS3U ESP32S3 Development Kit with USB-A from M5Stack is a compact microcontroller development board in a USB flash drive-style form factor based on the ESP32-S3FN8. The board integrates a dual-core Xtensa LX7 processor running at up to 240 MHz, 8 MB flash, and 2.4 GHz Wi‑Fi. With its USB Type-A interface supporting OTG and USB Serial/JTAG, it is suited to compact embedded and IoT designs requiring direct USB connectivity.

Integrated peripherals include a PDM microphone, an infrared emitter, a programmable WS2812 RGB LED, a button, one Grove port, and a 6-pin 2.54 mm header. The header exposes GND, VIN_5V, and signals G14, G17, G42, and G40. Supported development environments include UiFlow2, Arduino IDE, ESP-IDF, and PlatformIO.
