Description

Atom-Matrix is a very compact development board in the M5Stack development kit series, with a size of only 24.0 x 24.0 mm, offering more GPIO for user customization, making it ideal for embedded smart hardware. The main controller uses the ESP32-PICO-D4 solution, integrating a Wi-Fi module and having 4 MB of SPI flash. It has an onboard IR (infrared emitter), a 5*5 RGB Led matrix on the panel, a built-in IMU attitude sensor (MPU6886), with a programmable button hidden under the Neo Led matrix. The onboard USB Type-C interface allows for quick program upload and download, and there is also a HY2.0-4P interface for connecting peripherals. The back has an M2 screw hole for mounting.

Note

RGB Usage Precautions
When using the FastLED library, the recommended brightness value for the RGB LED is 20. Please do not set it to a high brightness value to avoid damaging the LED and acrylic screen. (In the Atom-Matrix library, we have mapped the appropriate brightness range to 0~100). Brightness should not be too high or fully on, as it can generate high temperatures leading to casing damage.
