ATOMS3 Lite is a programmable controller in the Atom Series, powered by the ESP32-S3 microcontroller. The main controller uses the ESP32-S3FN8 chip with 8MB SPI flash memory, integrated Wi-Fi functionality, and a built-in 3D antenna. It features a 5V to 3.3V power regulation circuit, infrared emitter, RGB status indicators, a programmable button, and GROVE/HY2.0-4P interfaces. The bottom of the device includes a power supply connector and 6 GPIO headers for expansion. An onboard USB Type-C interface supports firmware programming and serial communication. A mounting hole (M2) is provided on the back for secure installation. This device is suitable for embedded smart device applications.
