Evaluation Kit for TMD3721
TMD3721 EVM
The TMD3721 Evaluation Kit comes with everything needed to evaluate the TMD3721 ALS/Color and Proximity Sensor Module. The evaluation kit comprises of a main controller board with an FTDI controller, an industry standard micro USB interface (with a USB cable), a TMD3721 module daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the 3in1 (Proximity/ALS/RGB) sensor settings as the FTDI takes the TMD3721 I²C digital outputs to calculate Proximity, ALS and RGB.
