This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).
OCELL is a 0.5 inch OLED module designed as an Arduino shield and also available for other micro-controllers. It is one of the smallest Arduino display modules available.
You could connect it to Ardunio Micro directly without doing any PCB layout. It also works with other micro-controller boa..
