The ATOM Matrix, a tiny yet powerful gem in the M5Stack development kit series, measures just 24 x 24mm. This pocket - sized computer is equipped with an ESP32 - PICO - D4 chip that has built - in WiFi, Bluetooth, and 4MB of SPI flash memory. Despite its small form factor, it offers more GPIO pins, making it a top choice for embedded device development. The panel features a 5x5 RGB LED matrix and an infrared LED, along with a built - in IMU sensor (MPU6886). There's also a Grove/Stemma - compatible JST 2 - PH interface. Below the RGB LED matrix, there's a programmable button for added input options. The on - board USB Type - C is used for code loading and debugging. There's an M2 screw hole on the back for easy mounting. Unlike many M5Stack boards, it has no battery and is powered via the USB C port. Key features include being ESP32 PICO - based, having a programmable button, a 5x5 RGB LED matrix panel, an infrared LED, MPU6886 IMU, extendable pins and holes, and supporting the Arduino UIFlow program platform. Note: This is just the ATOM Matrix, no additional cables or batteries are included.
Using the ATOM Matrix is quite easy. First, connect it to your computer via the USB Type - C port. This will power the device and also let you load code using the Arduino UIFlow platform. The programmable button below the RGB LED matrix can be set up according to your needs for extra input functionality. The 5x5 RGB LED matrix and infrared LED can be programmed to create various visual and signal effects. The built - in IMU sensor can be used for motion - related projects. For mounting, use the M2 screw hole on the back. Remember, this device doesn't come with a battery, so always keep it connected to a power source via the USB C port. When it comes to maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. If you're using the extendable pins and holes, make sure the connections are secure to prevent any short - circuits or malfunctions.
