Compact ESP32 Development Kit with 5x5 RGB LED Matrix, BMI270 6-Axis IMU and Infrared Control
The M5Stack Atom Matrix ESP32 Dev Kit v1.1 is a compact programmable controller designed for motion sensing, infrared control, and visual-interaction applications. This updated version replaces the previous MPU6886 sensor with the BMI270 6-axis IMU, combining a 3-axis accelerometer and 3-axis gyroscope for improved motion and attitude detection. The board is based on the ESP32-PICO-D4 solution with integrated Wi-Fi connectivity and 4 MB SPI Flash, making it suitable for embedded development, smart-device control, and compact IoT prototypes.
For user interaction, Atom Matrix v1.1 integrates a 5x5 RGB LED matrix with a programmable button positioned beneath the display. The LED matrix can provide status indication, animations, and visual feedback, while the button supports configurable trigger actions. An onboard infrared emitter enables compatible remote-control applications, and expandable pins and interfaces provide access for custom sensors and external hardware. Its compact form factor makes Atom Matrix v1.1 useful for motion-sensing controllers, attitude-analysis projects, and smart-home control nodes.
