which is a 128 x 128 pixel monochrome CMOS unit. [Michael] hooked it up to an STM32F401 microcontroller, which reads out the sensor data and stores it on an SD card in the form of a bitmap image.

In this research, we have developed a three-layer color image sensor using organic films that detect only blue and only green light, layered vertically over a CMOS *1 image sensor that detects red ...
