The M5Stack Unit Colour (TCS3472) detects colours and sends RGB values over I2C, so it’s designed to be used with M5Stack boards and other I2C-capable microcontrollers. The M5Stack Unit Colour is a colour recognition unit that integrates a TCS3472 colour light digital converter, capable of converting detected colour values into RGB data and returning it to the M5Core. This unit communicates with the M5Core via the PORT A interface (I2C), with an I2C address of 0x29.
