JPEG 2M Pixel Color Camera Serial Interface(TTL level)

Description

LS-Y201-2MP is LinkSprite’s new generation high resolution serial port camera module. Its resolution is 2 million pixel. It can captures high resolution pictures using the serial port. LS-Y201-2MP is a modular design that outputs JPEG images through UART, and can be easily integrated into existing design.
