Overview
Pi4 Microscope Kit is for Raspberry Pi 4th generation. It uses the original 12-megapixel camera module of Raspberry Pi with a 6mm fixed-focus wide-angle lens, and a 4.3-inch 800x480 pixel DSI touch screen as the display screen. It is easy to assemble and more convenient to preview the camera screen.
