شیلد GSM چهار باند با داشتن جک 3.5 میلی متری صدا می تواند برای مدیریت تماس و انجام مکالمه مورد استفاده قرار گیرد. همچنین این شیلد با قابلیت تشخیص DTMF می تواند در کنار میکروکنترلرهای مختلف مانند آردوینو جهت هوشمند سازی سیستم های خانگی و صنعتی به کار برده شود. پروتکل ارتباطی این شیلد TTL می باشد که برای اتصال آن به کامپیوتر و ارسال دیتا می توان از تبدیل چند کاره موجود در محصولات مرتبط کالا استفاده نمود. این
از نوع LCC بوده و GPRS را تا بیش از 85.6 کیلوبیت بر ثانیه پشتیبانی می کند. ابعاد کوچک آن این قابلیت را به ماژول می دهد تا بتواند در طیف گسترده ای از دستگاه ها مانند تلفن های هوشمند، PDA ها و غیره مورد استفاده قرار گیرد.
Description:
SIM800C is a quad-band GSM/GPRS module that works on frequencies GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz.
SIM800C features GPRS multi-slot class10/class12 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. It is an LCC type module that supports GPRS up to 85.6kbps data transfer. It has a strong extension capability with abundant interfaces including UART, USB2.0, GPIO, etc. The module provides much flexibility and ease of integration for customer's applications.With a tiny configuration of 17.6*15.7*2.3mm, SIM800C can meet almost all the space requirements in customers’ applications, such as smartphones, PDAs, and other mobile devices.
SIM800C is an SMT package with 42 pads and provides all hardware interfaces between the module and customers’ boards.
The power interface supports 5-26V voltage input. when the voltage is 5-9V, the power adapter current can provide no less than 2A. (Support lithium batteries 3.6-4.2V)
The communication interface is a TTL level serial port. Fully compatible with Arduino, and compatible with other 5V, 3.3V, 2.85V systems.
The hardware serial port (D0 D1) or the software serial port (D7 D8) can be selected through the jumper cap.
It supports MICRO SIMCARD, four-segment headphone jack (I type), updates SIM800C firmware via USB or serial port.
It can be upgraded to a development board with a Bluetooth version.
The onboard TVS tube, SIM card protection IC, two 100UF tantalum capacitors, and other methods make the performance of the development board stable.

Aruduino SIM800C Shield Software:
It provided By TTL level serial communication with external systems, the default system can communicate directly with 5V, no level matching. And 3.3V systems, communication systems at 2.85V, need to do a bit of hardware processing.
The communication interface (command) for the AT command, that is, the control module functions entirely through AT commands to achieve, such as call control module using ATD .
