ams OSRAM TCS3720 Optical Sensor Evaluation Kit includes everything needed to evaluate the TCS3720 ALS/Color and Proximity Sensors. The hardware comprises the EVM Controller, the TCS3720 EVM daughter card, and a USB interface cable. The EVM controller board provides power and I2C communication to the daughter card through a seven-pin connector. When the EVM controller is connected to the PC via USB, a green LED indicates the system receives power. The LED will be turned off when the GUI program is started.
