SparkFun Spectral Sensor Breakout - AS7262
Visible (Qwiic)
SEN-14347 RoHS Open Source Hardware
The SparkFun AS7262 Visible Spectral Sensor Breakout brings spectroscopy to the palm of your
hand, making it easier than ever 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 I
2
C interface and serial interface using AT commands. Hookup is easy, thanks to 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. You’ll be
ready to upload a sketch to start taking spectroscopy measurements in no time.
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 for
you to illuminate objects that you will try 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 I
2
C 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 mean you can’t hook it up wrong.
