Adafruit AS7341 10-Channel Light / Color Sensor Breakout - STEMMA QT/Qwiic
The Adafruit AS7341 breakout is a high-precision 10-channel spectral color sensor with integrated flicker detection, designed for easy integration via I2C and STEMMA QT/Qwiic connectors. It provides detailed spectral analysis across the visible and near-infrared spectrum, compatible with 3.3V and 5V systems like Arduino, Raspberry Pi, and ESP32.
Features
- 10-channel spectral sensor with 8 visible (415nm–680nm), clear, and NIR channels.
- Integrated 16-bit ADC and Super MUX (SMUX) for flexible sensor routing.
- On-chip ambient light flicker detection (e.g., 50/60Hz).
- STEMMA QT / Qwiic connectors for solderless I2C connection.
- 3.3V/5V logic compatible with level-shifting circuitry.

The AS7341 is a multi-channel spectrometer IC that measures not just light intensity but the precise spectral composition across ten distinct optical channels. Its 3mm x 2mm silicon die utilizes nano-optic interference filters to isolate eight overlapping bands in the visible spectrum (415nm, 445nm, 480nm, 515nm, 555nm, 590nm, 630nm, 680nm), plus dedicated clear and near-infrared (NIR) channels for comprehensive light analysis.
Signal conditioning is handled by an integrated 16-bit, 6-channel analog-to-digital converter (ADC). A configurable Super MUX (SMUX) routes any of the eleven sensor elements (ten light channels plus flicker detector) to the available ADC inputs. This architecture enables high-resolution spectral power distribution measurements, accurate Correlated Color Temperature (CCT) calculation, and detection of AC mains light flicker, making it suitable for lab-grade applications.
The breakout board provides robust I2C communication, GPIO pins for external triggering or synchronization, and built-in level shifting for seamless operation with 3.3V or 5V microcontrollers and single-board computers.
