Pinouts and expansion options for the Atom Matrix ESP32 module
Despite its compact dimensions, the module offers extensive expansion options thanks to the Grove HY2.0-4P connector . The connector provides a 5V power supply, ground, and GPIO26 and GPIO32 lines, which can be used to communicate with additional modules or control your own peripherals. Internally, the microcontroller also uses dedicated lines for the LED matrix, user button, IR emitter, and the I2C bus for communicating with the BMI270 sensor. This solution allows you to simultaneously use built-in functions and expand the device's capabilities with additional sensors, displays, or actuators. The USB Type-C connector enables programming, serial communication, and powering the module without the need for additional adapters.
Atom Matrix v1.1 vs. Atom Matrix - the most important differences
The biggest change in Atom Matrix v1.1 is the use of a modern BMI270 sensor instead of the previously used MPU6886. The new chip provides higher accuracy in orientation measurements and faster response to changes in device position . Thanks to the improved IMU, the module is more suitable for applications related to motion analysis, gesture control, robotics, and spatial orientation tracking systems. Other key design elements, such as the ESP32-PICO-D4, 5x5 RGB matrix, IR emitter, and programmable button, remain unchanged.
The USB Type-C connector enables programming, serial communication and powering the module.
Atom Matrix v1.1 is compatible with Arduino IDE, ESP-IDF, PlatformIO and UiFlow.
Programming the Atom Matrix ESP32 v1.1 module
Atom Matrix v1.1 offers extensive programming capabilities, making it suitable for both educational projects and professional IoT systems. The module is fully compatible with the Arduino IDE, ESP-IDF, PlatformIO, and the UiFlow 1 and UiFlow 2 graphical environments , allowing for a selection of tools tailored to the user's experience level. Beginners can use the UiFlow platforms, which allow for building applications using a block-based approach without writing code . More advanced users can access the full capabilities of the ESP32 through the Arduino IDE, PlatformIO, or the native ESP-IDF environment, utilizing ready-made libraries for the RGB matrix, BMI270 sensor, Wi-Fi communication, IR transmission, and Grove-connected devices. Thanks to the widespread popularity of the ESP32 platform, thousands of examples, libraries, and community projects are available, significantly accelerating the development of their own devices.
