Description

Atom-Matrix v1.1 is an iterative upgrade of the Atom-Matrix. This product replaces the MPU6886 from the previous generation with a BMI270 six-axis IMU sensor, effectively improving attitude detection accuracy and response speed, making it better suited for high-precision applications such as motion capture and attitude control. The main controller adopts the ESP32-PICO-D4 solution with integrated Wi-Fi connectivity and onboard 4 MB SPI flash. It also features an infrared emitter and a 5×5 RGB LED matrix display. A programmable button is located beneath the LED matrix, supporting custom trigger logic for convenient implementation of IR remote control, visual interaction, and command triggering. This product is ideal for embedded development and prototyping scenarios that require high-precision attitude detection, infrared remote control, and visual interactive feedback.
