AS7262 Spectral Sensor Visible Light SparkFun Qwiic

The SparkFun AS7262 measures visible light in 6 channels, showing how materials absorb and reflect different wavelengths. It communicates via I2C or via a serial interface with AT commands. It is connected via the Qwiic connectors or by soldering on wires or pin headers. An LED on the board illuminates the object, and two pins accept your own lamp.

Important: The operating voltage and logic must not exceed 3.6 V. A level converter is required on a 5 V Arduino.

Recommended Accessories:

• Logic Level Converter 2-Channel 5V / 3.3V
• Pin header male 1 X 40 pole RM 2.54mm straight short pin

Features:

• 2× Qwiic connectors
• LED on the board, can be disconnected with JP4
• Pull-up resistors can be disconnected with JP1
• Serial interface: open solder bridge JP1 and close JP2

Application Examples:

• Comparing materials by their spectrum
• Measuring colours and light sources
