ATOM Matrix , which has a size of only 24 * 24mm, is the most compact development board in the M5Stack development kit series. It provides more GPIO pins and is very suitable for handy and miniature embedded device development. The main control adopts the ESP32-PICO-D4 chip, which comes integrated with Wi-Fi technologies and has 4MB of integrated SPI flash memory. The Atom board provides an Infra-Red LED along with the 5 * 5 RGB LED matrix on the panel, a built-in IMU sensor (MPU6886), and a HY2.0 interface. A general purpose programmable button is proved below the RGB Led matrix to enable users to add input support to their various projects. The on-board USB interface (Type-C) enables rapid program uploading and execution. One M2 screw hole is provided on the back for mounting the board.

Note: When using FastLED lib, the recommended brightness of RGB LED is 20. Please do not set it to a high brightness value to avoid damage to the LED and acrylic screen. (In ATOM lib, we have mapped its appropriate brightness range to 0~100)，The brightness cannot set too high and cannot be fully bright for a long time, which will cause high temperature and maybe damage to the shell.
