• Description
• 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 I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board --- simply plug one *** 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.
• Note:The I2C address of the AS7262 is 0x49 and is hardware defined. A multiplexer/Mux is required to communicate to multiple AS7262 sensors on a single bus. If you need to *** more than one AS7262 sensor consider using the Qwiic Mux Breakout.
• 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 *** 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.
