A USB-powered board can work through an A-to-C cable yet stay dead on a C-to-C supply when its receptacle lacks the required Rd pull-down on both CC1 and CC2.
USB-C Board Works With A-to-C but Not C-to-C? Check Both CC Pull-Downs Read More
Adafruit’s TCS3448 breakout exposes 14 spectral channels, 1 kHz flicker detection and an Arduino library—but AS7343 projects must account for its fixed 0x59 I²C address.
