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.
