C124

C124 is an AtomS3 Lite ESP32S3 dev kit. The 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 and IoT nodes.
