TL;DR
The Adafruit AS7343 is a new 14-channel multi-spectral sensor breakout that enhances the capabilities of its predecessor, the AS7341. This updated version now includes 12 channels that range from visible light into near-infrared (380nm to 1000nm), along with clear and flicker detection. It maintains the same footprint and pinout as the AS7341, making it easy to integrate into existing projects without needing to modify wiring or enclosures.
