MC-7725
300,000 Pixel Serial JPEG Camera Module
Overview
The Serial Camera, built in snapshot, JPEG compression and serial interface communication module, can be attached to computer and any other embedded devices performing as a video camera or a JPEG compressed still camera for imaging applications. It uses an Omni Vision CMOS OV7725 sensor(OV7725 is also used in the camera of iPhone, it is much better than others) along with a JPEG compression chip that provides a low cost and low powered camera system. Its on-board Serial interface is suitable for a direct connection to any host micro-controller UART. The JPEG picture can be captured via serial commands, which makes monitoring so easy.
