It includes camera, screen and control board. Control board is placed on the back of the screen. Camera sensor generates image data which is then processed real-timely by control board and displayed on the screen.
The Screen is 2.8 ' and 65K color, supporting touch TFT function. Camera is 30W Pixel OV7670 camera, which can supply distinct image for normal use. Control board is integrated with ATmega 32. So it is compatible with Arduino, which makes it possible to communicate with Arduino easily.
Many interfaces on the control board are still not used, including 4-channel ADC, 1 channel USART, ISP port and 2 channel PWM, which makes function development much easier. 5V power is supplied to the control board via USB port, without any special requirement for power module.
OV7670 screen's power supply is 2.8 ~ 3.0V, which is TTL level for most of MCU. TF/SD card can be connected to SPI port, which makes image storage possible. Camera interface is plug-in mode. It is very easy to connect or disconnect with control board. Control board and camera can be used separately.
The chip is loaded with a firmware, so it can work as electronics photo frame, displaying pictures from TF card, and as video recorder. However, so far it can display video collected by camera. It can not store the video. No code has made it true so far, but you deserve to try.
Note: Pictures shown above are just for reference, there may be minor differences in color and layout based on the revision number.
