2. Product Concept
The M10 is a Quad-band GSM/GPRS engine that works at frequency bands of GSM850 and PCS
1900. The M10 features GPRS multi-slot class 12 and supports the GPRS coding schemes CS-1,
CS-2, CS-3 and CS-4.
The M10 is an SMD type module with 64-pin pads and a tiny profile of 29mm x 29mm x 3.6 mm
(the thickness of PCB is 1.6mm), which can fit into almost all customers’ applications. It provides
all hardware interfaces between the module and customer’ host board.
 External controller can communicate with M10 through its main UART port.
 Two audio channels include two microphone inputs and two speaker outputs, which can be
easily configured by AT command.
The module is designed with power saving technique so that the current consumption could be very
low.
TCP/IP protocol stack has been integrated in the module. Moreover, extended TCP/IP AT
commands have been developed for customer to use the internal TCP/IP protocol easily, which is
very useful for data transfer application.
The module is fully RoHS compliant to EU regulation.
