1 Overview
is an ambient light sensor (ALS) with a digital output integrated circuit. It uses a two-wire interface
that works with the I
2
C protocol making it ideal for many applications. The OPT4001YMN is the picostar package
version of the OPT4001 device. The picostar package achieves very small size and thickness and orients
with the photodiode facing down and senses light through a cutout in the board. This requires the sensor be
soldered to a flex PCB in most applications to maximize the field of view of the sensor. The OPT4001YMNEVM
is a platform for evaluating the performance of the OPT4001 under various conditions. The OPT4001YMNEVM
consists of two PCBs. The first is the OPTMB EVM board, which is a motherboard. This board communicates
with a computer through USB connection and provides power and sends and receives appropriate digital signals
with the
IC. The motherboard will relay USB commands from the EVM GUI software running on
the PC to the
2
C. The second is the OPT4001YMN coupon board, which contains the
OPT4001YMN and its support circuitry. The coupon board consists of a flex PCB soldered to a rigid board. This
allows the coupon to be easily plugged and unplugged as the rigid board adds strength to the flex board.
