ATOM Matrix is the most compact development board in the M5Stack development kit series yet with a size of only 24 * 24mm. 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 PH2.0 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: We have set the brightness of RGB LED limited to 20. Pls DO NOT set it higher to avoid damaging the LED and acrylic screen.

I still didnt got my order
The ATOM Matrix ESP32 dev kits are great little devices! The Arduino code samples are not completely functional, but I was able to get apps running once "M5Stick-C" was chosen in the Arduino IDE.
The ATOM Matrix does not come with a battery, but a coin cell should be about the right size.
Looking forward to more products from M5Stack!
I used it for a little MicroPython project and had no troubles, see https://www.hackster.io/andreas-motzek/mqtt-enabled-scrolling-text-with-atom-matrix-and-micropython-98f29e
Excellent product !!
