There are several Raspberry Pi based camera projects. PiJuice decided to build something even smaller, so he came up with compact camera project. He’s chosen Raspberry Pi A+ which is smallest Rasberry Pi. Next thing he had to deal with was power supply. He used PiJuice module which takes care of charging battery and generating necessary voltage for Raspberry Pi.
There is one obvious choice for camera module so nothing to add here. On a back side of camera he attached Adafruit 2.2” TFT screen which comes with four navigation buttons. He also laser cut basic enclosure to make it look like real camera that can be taken anywhere for capturing photos and videos.
