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.

USB Driver

Atom-Matrix may not work without a driver on some systems. You can resolve this issue by manually installing the FTDI VCP driver.

1. Select the driver file that matches your operating system from the list below, download it, and extract it. You can also visit the FTDI Chip official website for additional FTDI driver versions.

2. Connect the device to your PC, open Device Manager, and install the FTDI driver (the screenshot below uses Windows 10 as an example). (Note: On some systems, you may need to install the driver twice for it to take effect. The unrecognized device is usually named M5Stack or USB Serial.)
