Pimoroni AS7262 6-Channel Spectral Sensor Breakout - I2C/UART Interface
The Pimoroni AS7262 Breakout is a 6-channel visible light spectral sensor-on-chip, providing precise color identification and spectral analysis. It operates on 3.3V or 5V logic and communicates via I2C or UART, making it compatible with Raspberry Pi, Arduino, and other microcontrollers for advanced color sensing applications.
Features
- Six discrete spectral channels (450, 500, 550, 570, 600, 650nm) for precise visible light analysis.
- Dual communication interfaces: I2C (address 0x49) and serial UART for flexible system integration.
- Integrated programmable LED drivers with reverse polarity protection for controlled illumination.
- High-resolution 16-bit ADC ensures accurate spectral data capture and digital access.
- Raspberry Pi-compatible pinout with official Python and C++/MicroPython libraries for rapid prototyping.

The AS7262 sensor utilizes advanced nano-optic deposited interference filter technology integrated directly into CMOS silicon, creating six Gaussian optical filters with a full-width half-max (FWHM) of 40nm across the 430nm to 670nm visible spectrum. This design enables cost-effective, highly integrated spectral identification without external optical components.
The breakout module provides a built-in aperture to control incident light and includes on-board illumination LEDs. It is designed for robust operation from -40°C to +85°C, supporting applications requiring stable performance in varying environmental conditions. The electronic shutter functionality via programmable current drivers allows for precise measurement control in different lighting scenarios.
