Sparkfun Spectral Sensor Breakout - As7262 Visible (Qwiic) makes it easier to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7262 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. The Qwiic connectors attached to the board simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic Shields, then stack the board on a development board.
The AS7262 spectrometer detects wavelengths in the visible range at 450, 500, 550, 570, 600 and 650nm of light each with 40nm of full-width half-max detection. The board also has multiple ways to illuminate objects to measure for a more accurate spectroscopy reading. There is an onboard LED that has been picked out specifically for this task, as well as two pins to solder your own LED into.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections.
