Unit Color is a high-precision RGB color recognition unit. It integrates the TCS3472 color light-to-digital converter, supporting four-channel RGBC (Red, Green, Blue, Clear) measurement, enabling accurate conversion of ambient light into RGB data. The unit communicates via the I2C interface (0x29) and features an integrated LED fill-light system to ensure accurate color recognition under various lighting conditions. With a LEGO-compatible mounting hole design, it can be flexibly attached to… (M5Stack U009)
