Description
The module is equipped with a sensor of spectrum, i.e. the spectrum of visible light, allows you to measure and to characterize how different materials absorb and reflect light waves. It detects the wavelength range seen in the light of 450, 500, 550, 570, 600 and 650 nm, each with a 40 nm of full width of half of maximum detection. The sensor communicates using I2C and UART interface via AT commands. It has two connectors Qwiic, pitch of 1 mm and the connectors for soldering the goldpin strap of 2.54 mm(sold separately).
The board has a built-in LED with a power of 5700K, which is used to illuminate the objects. You can solder any LED operating at a voltage of 3.3 V.

PinsModule AS7262 has two communication interfaces: I2C and serial. The I2C interface is default. To use the serial interface, you must remove the tin located on jumper JP1 and put it on jumper JP2, located on the other side of the board. For serial communication with the computer, use a converter USB-to-Serial. On the board are two connectors Qwiic of 1 mm and output of 2x 6-pin for soldering the goldpin strap of 2.54 mm.
