Description

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

Package List

  • 1 X [CAM_JPEG_RS232][201201002]
  • 1 X [IT_CAM_CAB ][AA102]

Features

Application Ideas

  • Different image capture systems
  • Environmental monitoring
  • Industry monitoring
  • Medical equipment
  • Video phone
  • Security
  • Vehicle based GPS

Cautions

The warnings and wrong operations possible cause dangerous.


Schematic
