## Description

Measure visible and near-infrared light with a compact Qwiic breakout based on the AS7343 multi-spectral sensor. It covers approximately 380nm to 1000nm and is suited to reflected, emitted and transmitted light measurements for spectroscopy tasks such as colour matching and spectral signature analysis.The AS7343 uses a 5x5 photodiode array with 14 channels, including 11 visible-spectrum bands plus dedicated near-infrared and flicker detection photodiodes. It is designed for high sensitivity, including low-light measurements and operation behind tinted glass or other external filters.Communication is over I2C, with two Qwiic connectors for solderless connection, plus 0.1-inch PTHs for SDA, SCL, power and additional pins. The breakout includes a white sensing LED, pads for adding your own sensing LED, a 1.8V regulator and level shifting from the 3.3V Qwiic bus.Documentation and software support include a schematic, KiCad files, board dimensions, AS7343 datasheet, hookup guide, SparkFun AS7343 Arduino Library, SparkFun AS7343 Python Package and GitHub repository.Features:Sensor: 14-Channel Multi-Spectral SensorSpectrum: Measures both Visible Spectrum and Near-InfraredDetection: Flicker DetectionSensitivity: High SensitivityLow-light use: Operates in low-light or behind dark glass/other external filtersLED control: Integrated LED DriverGPIO: 1 GPIO for measurement/LED synchronizing (Defaults as Output)Connectors: 2x Qwiic ConnectorsHeaders: 0.1"-Spaced PTHsI2C pins: SDA/SCLInterrupt: INT (Active Low)GPIO pin: GPIOPower: 3.3VGround: GNDLEDs: LEDsPower LED: Power (Red)Sensing LED: White (Sensing)Optional LED: PTHs for User-Populated Sensing LED (Optional)Regulation: 1.8V Voltage RegulatorSpecifications:Wavelength Range: ~380nm - 1000nmVisible spectrum channels: 11 Channels on the Visible SpectrumNear-infrared channels: 1 Channel on Near-InfraredClear channel: 1 "Clear" Channel for entire Visible SpectrumNear-infrared photodiode range: 845-865 nmSensor supply voltage: 1.8V Supply VoltageSensor active current: 210µA (Typ.) - 280µA (Max.)Sensor idle current: 40µA (Typ.) - 60µA (Max.)Sensor sleep current: 0.7µA (Typ.) - 5µA (Max.)Qwiic voltage: 3.3VBoard dimensions: 1 in. by 1 in.PTH spacing: 0.1"Breakout active current: 697µA@3.3VBreakout idle current: 264µA@3.3VBreakout sleep current: 3µA@3.3VBoard measurement current without white LED on: ~697µABoard measurement current with white LED on: ~4.26mAA handy sensor breakout for colour sensing, spectroscopy experiments, material comparison and light measurement projects using the SparkFun Qwiic ecosystem.
