Description

Atom-Lite is a very compact development board in the M5Stack development kit series, with a size of only 24.0 x 24.0 mm, providing more GPIO for user customization, making it very suitable for embedded smart hardware development. The main controller uses the ESP32-PICO-D4 solution, integrates a Wi-Fi module, has a built-in 3D antenna, and features 4 MB of SPI flash, providing Infra-Red, RGB Led, button, and GROVE/HY2.0 interfaces. The onboard USB Type-C interface allows for quick program upload and download, and there is an M2 screw hole on the back for fixing.
