Why it belongs on the bench

M5Stack AtomS3 is a 24 mm ESP32-S3 controller with a 0.85-inch color display, programmable push control, MPU6886 IMU, infrared emitter and Grove-style expansion. It is best matched to compact embedded interfaces and the catalogue’s manufacturer user demo, which exercises Wi-Fi scanning, I2C, UART, PWM, analog input, infrared and motion sensing. The cited AtomS3 model is marked end-of-life in M5Stack’s store, so confirm that a listing is this screened AtomS3 rather than another ATOM-family variant. The official demo documents PlatformIO and fixed board-specific pins; firmware for another ATOM model should not be assumed compatible.
