Atom-Matrix v1.1

SKU:C008-B-V11

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.

Note

When using the RGB LEDs, it is recommended to set them to a moderate brightness level. Avoid setting excessively high brightness values, as this may damage the LEDs and the acrylic display.

USB Driver

Atom-Matrix v1.1 may not work without a driver on some systems. You can resolve this issue by manually installing the FTDI VCP driver.

1. Select the driver file that matches your operating system from the list below, download it, and extract it. You can also visit the FTDI Chip official website for additional FTDI driver versions.

2. Connect the device to your PC, open Device Manager, and install the FTDI driver (the screenshot below uses Windows 10 as an example). (Note: On some systems, you may need to install the driver twice for it to take effect. The unrecognized device is usually named M5Stack or USB Serial.)
