This means that you can use it to detect much better than the human eye is capable of, what color or colors of light is present.\u003c\/p\u003e\n\u003cp\u003eThe TCS3448 packs within its 3x2mm footprint 25 photodiodes that can detect 11 separate, overlapping bands of visible light, plus one near infrared, one clear and a flicker channel for 14 channels total. Compared to the AS7341, this sensor has 4 more light channels - but you'll need to use a new firmware driver since it's not back-compatible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe TCS3448 is ams Osram's 'refresh' of the AS7343\u003c\/strong\u003e, so it's an upgrade from the AS7341 and has some slight improvements\/changes over the AS7343: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eI2C address changed from 0x39 to 0x59.\u003c\/li\u003e\n\u003cli\u003eRetuned optical filters: channel centers move by a few nanometers and several visible channels have higher responsivity especially violet\/blue and the F8 far-red channel.\u003c\/li\u003e\n\u003cli\u003eSensitivity is not higher everywhere; NIR response is lower.\u003c\/li\u003e\n\u003cli\u003eFirmware is not 100% drop-in!

It's kind of like a mini spectroscopy sensor. This is possible thanks to the impressive collection of sensors in the TCS3448 being routed through 6 independent 16-bit ADCs that take the raw measurements and convert them to digital values that can be read out over I2C.\u003c\/p\u003e\n\u003cp\u003e14 readable individual sensor elements (13 light channels plus flicker detection) don’t exactly fit through a 6-channel ADC all at once, so the chip includes a so-called Super MUX (SMUX) that allows you to route the signal from any sensor to any ADC channel. The sensor also has GPIO and interrupt pins that can allow it to communicate directly with other sensors, or the microcontroller itself.\u003c\/p\u003e\n\u003cp\u003eAll of this capability is made accessible by mounting the sensor on a STEMMA QT form factor breakout board, complete with level shifting circuitry and \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eSparkFun Qwiic\u003c\/a\u003e compatible \u003ca rel=\"noopener\" href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\" target=\"_blank\"\u003eStemma QT\u003c\/a\u003e connectors.
