Designed for global market, SIM300C is a Tri-band GSM/GPRS engine that works on frequencies of EGSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz.SIM300C features GPRS multi-slot class 10/ class8(optional) capability and support the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.

With a tiny configuration of 50mm x 33mm x 6.2mm, SIM300C can fit almost all the space requirement in your industrial application, such as M2M, and mobile data communication system etc. With the charge circuit integrated inside the SIM300C, it is very suitable for the battery power application.

The physical interface to the mobile application is made through a 60 pins DIP connector, which provides all hardware interfaces between the module and customers’ boards except the RF antenna interface.
* The keypad and SPI display interface will give you the flexibility to develop customized applications.
* Serial port and Debug port can help you easily develop your applications.
* Two audio channels include two microphones inputs and two speaker outputs. This can be easily configured by AT command.
* Charge interface
The SIM300C provides RF antenna interface with two alternatives: antenna connector and antenna pad. The antenna connector is MURATA MM9329-2700. And customer’s antenna can be soldered to the antenna pad.
The SIM300C is designed with power saving technique; the current consumption is as low as 2.5mA in SLEEP mode.
The SIM300C is integrated with the TCP/IP protocol, extended TCP/IP AT commands are developed for customers to use the TCP/IP protocol easily, which is very useful for those data transfer applications
