This module uses TCS3200D, which is the upgraded version of TCS230D. TCS3200 is a static object color detection chip which can output different frequency based on different color sensed and then MCU can read the RGB color via frequency collection and conversion.
The Break-out board has TCS3200 color sensor
Support 3V-5V voltage input
Four bright white LED, on-board, can illuminate the object which does not emit light itself. Controllable light-emitting tube.
S1 S2 S3 S4 can be used as the pull-up or pull-down resistors on board.
PCB Size: 23mm X 30mm
