SparkFun AS7262 Spectral Sensor Breakout (Qwiic)
Overview
The SparkFun SEN-14347 is a 6-channel visible light spectral sensor breakout board utilizing the ams AS7262. It provides 16-bit measurements across the 450nm to 650nm range with 40nm Full-Width Half-Max (FWHM) filters, allowing for precise color identification and spectral analysis. The board features the Qwiic connection system for solderless I2C integration and includes an onboard LED for illuminating samples.
Why Choose This Part
The sensor uses silicon interference filters deposited directly on the CMOS die, providing high stability over time and temperature compared to traditional filters. The integrated Qwiic ports and 2.7V to 3.6V operating range make it easy to daisy-chain with other sensors and interface with modern 3.3V microcontrollers without complex level shifting.
Applications
Key Specifications
Getting Started
Connect the board to a Qwiic-compatible microcontroller such as an ESP32 or Arduino using a Qwiic cable to begin reading data over I2C. SparkFun provides a dedicated Arduino library that simplifies calibration and allows for easy configuration of the 16-bit ADC and programmable LED driver.
