AS7343 14-Channel Multi-Spectral Sensor Breakout

Detect fourteen distinct channels of light (from 380 nm to 1000 nm) with this versatile spectral sensor.

The AS7343 is a 14-channel multi-purpose spectral sensor. It is optimized for reflective, transmissive and emissive measurements including color matching, fluid or reagent analysis or general spectral reconstruction. It can detect 14 spectral channels - 12 in the visible spectrum (VIS) to near-infrared (NIR) range, a clear channel and flicker channel.

This I2C breakout is compatible with our modular Breakout Garden system, which is designed to make working with breakouts straightforward - just pop it into a Breakout Garden slot and start to grow your project, create, and code. It's also Qw/ST compatible, which means it can be connected up to any microcontroller or add-on with a Qwiic or STEMMA QT connector using a Qw/ST cable - no soldering required!
