The SparkFun AS7262 Visible Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easy to measure and characterise how different materials absorb and reflect different wavelengths of light. It communicates via both I²C and serial (AT commands), and features Qwiic connectors for plug-and-play hookup — no soldering required.

The AS7262 detects six wavelengths in the visible spectrum — 450, 500, 550, 570, 600, and 650 nm — each with 40 nm full-width half-maximum (FWHM) detection. An onboard LED is included for illuminating samples, plus two pads for soldering your own LED.
