M5Stack ATOM Matrix ESP32 Development Kit

The Atom Matrix, measuring just 24 x 24 mm, is the most compact development board in the M5Stack development kit series. It offers more GPIO pins and is ideal for developing handy and miniaturized embedded devices. The main controller uses the ESP32-PICO-D4 chip, which integrates Wi-Fi and Bluetooth technologies and features 4 MB of built-in SPI flash memory. The Atom board includes an infrared LED as well as a 5 x 5 RGB LED matrix on the panel, an integrated IMU sensor (MPU6886), and a YH2.0 interface. Beneath the RGB LED matrix is a universally programmable button that allows users to add input options to their various projects. The integrated USB interface (Type-C) enables quick uploading and execution of programs. On the back, there is an M2 screw hole for mounting the board.
