C328R
JPEG Camera Module
W/ UART Interface
General Description
The C328R is VGA camera module performs as a JPEG compressed still camera and can be attached to a
wireless or PDA host. Users can send out a snapshot command from the host in order to capture a full
resolution single-frame still picture. The picture is then compressed by the JPEG engine and transferred to
the host thru serial port.

Note: In order to facilitate people for better understanding the communication with the module, we have developed an EV
kit, C328-EV232, for user to run under PC Windows environment. However, this module is not designed for PC application.
Such PC evaluation is only for better understanding of command control.
