ATOM Matrix , which has a size of
only 24 * 24mm, is the most compact development board in the M5Stack development kit series. It provides more GPIO pins and is very suitable for handy and miniature embedded device development. The main control adopts the
ESP32-PICO-D4 chip, which comes integrated with
Wi-Fi and Bluetooth technologies and has
4MB of integrated SPI flash memory. The Atom board provides an Infra-Red LED along with the
5 * 5 RGB LED matrix on the panel, a built-in
IMU sensor (MPU6886), and a HY2.0 interface. A general purpose programmable button is provied below the RGB Led matrix to enable users to add input support to their various projects. The on-board USB interface (Type-C) enables rapid program uploading and execution. One M2 screw hole is provided on the back for mounting the board.
Note: When using FastLED lib, the recommended brightness of RGB LED is 20. Please do not set it to a high brightness value to avoid damage to the LED and acrylic screen. (In ATOM lib, we have mapped its appropriate brightness range to 0~100)
UnitV/M5StickV/M5StickC/ATOM may not work without driver in some systems. Users can manually install
to fix this problem. Take the win10 environment as an example, download the driver file that matches the operating system, decompress it, and install it through the device manager. (Note: In some system environments, the driver needs to be installed twice for the driver to take effect. The unrecognized device name is usually
USB Serial. Windows recommends using the driver file to install directly in the device manager (custom Update), the executable file installation method may not work properly).

EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification.
Test whether the RGB LED and keys work normally by using the matrix screen text scroll display and key count function.
