Description
The ATOM Matrix is the most compact development board in the M5Stack series, measuring only 24 x 24mm. It features the powerful ESP32-PICO-D4 chip with integrated WiFi, Bluetooth®, and 4MB of SPI flash memory. This tiny powerhouse provides more GPIO pins, making it ideal for embedded device development.
The board includes a 5×5 RGB LED matrix panel, an infrared LED, a built-in MPU6886 IMU sensor, and a Grove/Stemma-compatible JST 2-PH interface. A programmable button is conveniently located below the LED matrix for user input. It is powered via a USB Type-C port and includes a mounting hole for easy installation.
Note that this product is the ATOM Matrix board only; no additional cables or batteries are included.
