Product Description

The M33 is a complete Quad-band GSM/GPRS module with 8-bit CCIR656, CMOS camera sensor interface which supports YUV422/YUV411/ YUV420 data format and up to 300K pixels CMOS camera input. It can be embedded in security device to implement photo taking, JPEG compression and MMS transfer. Customer can easily

develop the whole security equipment through Quectel solution. 

Featuring an industry-standard interface, the M33 delivers GSM/GPRS 850/900/1800/1900MHz  performance for voice, SMS, data, and fax in a form factor with extremely low power consumption. With a size configuration of 40mm x 32.2mm x 6mm and four soldering pins, M33 can be fixed in host PCB easily. A 300k pixels CMOS camera or CCIR656 interface digital video can be connected to M33 directly. Customer application implements the photo handling and transfer function through AT commands.
