PTC06 Serial Camera Specification General Description The PTC06 JPEG compression module performs as a video camera or 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. Features Small in size, 20x28mm VGA resolution, down sample to QVGA ( 640 x 480) Low power consumption, 5V operation UART interface support up to 115200 bps (default 115200 bps) Built-in JPEG CODEC Built in lens, optional User friendly command Pin Description Pin Description Power Ground GND Data Receive (3.3V TTL Level) RXD TXD Data Transmit (3.3V TTL Level) VCC Power 5V DC Analog Video output CVBS Guangzhou Putal Communication Technology Co., Ltd supports putal.com.cn PTC06 Serial Camera Specification Command Summary Command Function Configure interface speed image size INITIAL GET PICTURE Get image from the module Capture a still image SNAPSHOT Set the package size to transmit data from module to Host SET PACKAGE SIZE Reset the whole system RESET Provide the data length information.
