AtomS3-Lite

SKU:C124

Description

AtomS3-Lite is a programmable controller of the Atom series within the M5Stack development kit lineup, featuring ESP32-S3 as the main controller and measuring just 24.0 x 24.0 x 9.5mm. It adopts the ESP32-S3FN8 solution with 8MB SPI flash, integrated Wi-Fi, built-in 3D antenna, and a 5V to 3.3V power circuit. The device offers an IR transmitter LED, RGB status indicator, button, and HY2.0-4P interface. Power pins and six GPIO female headers are routed out at the bottom for easy expansion. The onboard USB Type-C port enables program download and serial communication, and an M2 screw hole on the back provides mounting options. This module is ideal for various embedded smart device applications.
