OPT4001YMNEVM TI评估板传感器EVAL BOARD FOR OPT4001 -环境光

　　Overview

　　The OPT4001 is an ambient light sensor (ALS) with a digital output intearated circuit, it uses a two-wire interfacethat works with the l2C protocol making it ideal for many applications. The OPT4001YMN is the picostar packageversion of the OPT4001 device. The picostar package achieves very small size and thickness and orientswith the photodiode facing down and senses light through a cutout in the board. This requires the sensor besoldered to a flex PCB in most applications to maximize the field of view of the sensor. The OPT4001YMNEVMis a platform for evaluating the performance of the OPT4001 under various conditions. The OPT4001YMNEVMconsists of two PCBs. The first is the OPTMB EVM board, which is a motherboard. This board communicateswith a computer through USB connection and provides power and sends and receives appropriate digital signalswith the OPT4001 lC. The motherboard will relay USB commands from the EVM GUl software running onthe PC to the OPT4001 lC through l12c. The second is the OPT4001YMN coupon board, which contains theOPT4001YMN and its support circuitry. The coupon board consists of a flex PcB soldered to a rigid board. Thisallows the coupon to be easilv plugged and unplugaed as the rigid board adds strenath to the flex board.
