The M5Stack ATOM Lite is the most compact development board for the ESP32, measuring just 24 x 24 mm. It features an ESP32-PICO-D4 microcontroller that integrates WiFi and Bluetooth technology and has 4 MB of built-in SPI flash memory. The ATOM board includes an infrared LED, a button, an RGB LED, and a PH2.0 interface. The integrated USB Type-C interface allows for quick uploading and execution of programs. An M2 screw hole is provided on the back for easy mounting of the ATOM. Various I/O ports are accessible on the back of the ATOM via a 2.54-pin header, which can be easily connected with a Dupont cable. The ATOM can be programmed using MicroPython or the Arduino IDE.
