Infrared sensor module To replicate Krejci’s design, you need an Arduino UNO Rev3 board, an AMG8833 infrared sensor module, and an 8×8 RGB LED matrix.

Built around an STM32H747XI microcontroller, internal processing comes from two cores: a 480MHz Arm Cortex-M7 and a 240MHx Cortex-M4. It is essentially DIN-rail module with relay outputs and sensor ...
