Mini TTL Serial Camera module

Mini TTL Serial Camera Module is a new generation industrial image acquisition processing camera module that include image acquisition, shooting control, data compression and serial transmission.

It can be used to snapshot high-definition image through serial interface. Serial camera module get JPEG image through a serial port, so this module can be easily integrated into the some device, and let the equipment device has image snapshot function. This is a new industrial image acquisition processing module that include image acquisition, shooting control, data compression and serial transmission.

Its built-in high-performance digital signal processing chip realizes high scale compression for the original image.

This module image output adopts standard JPEG format, which can be easily compatible with various image processing software.

It use 3-wire TTL level UART communication interface, it can be easily connected with MCU and other microprocessors thorugh 2.0mm space between interface.
