M5Stack ATOM Matrix ESP32 Development Kit features a 240MHz dual-core ESP32-PICO chip that comes integrated with Wi-Fi and Bluetooth® technologies. The board has a 4MB of integrated SPI flash memory and provides an Infrared (IR) LED, a built-in IMU sensor (MPU6886), and an HY2.0 interface. This ATOM matrix board provides more GPIOs for customization that are suitable for handy and miniature embedded device development. The board comes with a general-purpose programmable button that is provided below the RGB Led matrix. This enables users to add input support to their various projects. The ATOM matrix board operates at a 5V supply voltage and 0°C to 40°C temperature range. The development board is available in 24mm x 24mm x 14mm dimensions. Typical applications include the Internet of Things (IoT) terminal controller, IoT node, and wearable peripherals.
