Atom-Matrix

SKU:C008-B

Description

Atom-Matrix is an ultra-compact development board in the M5Stack series, measuring only 24.0 x 24.0 mm. It offers additional GPIOs for user customization and is ideal for embedded smart-hardware projects. Powered by the ESP32-PICO-D4 with an integrated Wi-Fi module and 4 MB SPI flash, the board carries an IR transmitter, a 5 × 5 RGB LED matrix, a built-in IMU (MPU6886), and a programmable button hidden beneath the Neo-LED matrix. A USB Type-C port enables quick program upload/download, and an HY2.0-4P connector is provided for peripheral expansion. An M2 mounting hole on the back allows secure installation.

Note

When using the FastLED library, a recommended brightness value for the RGB LEDs is 20. Do not set the brightness too high, or the LEDs and acrylic panel may be damaged. (In the Atom-Matrix library, we have mapped a suitable brightness range of 0–100.) Excessive brightness or full-on operation can generate high temperatures and damage the enclosure.
