Quad Band GSM
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.
Specifications:Quad-Band 850/ 900/ 1800/ 1900 MHzGPRS multi-slot class 10/12GPRS mobile station class BCompliant to GSM phase 2/2+2-in-1 headset jack
Features: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 battery (3.6-4.2V)The communication interface is a TTL level serial port. Fully compatible with Arduino, it is 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.Support for MICRO SIMCARD.Supports four-segment headphone jack (type I).Support for updating SIM800C firmware via USB or serial port.Can be upgraded to a development board with a Bluetooth version.The on-board TVS tube, SIM card protection IC, and two 100UF tantalum capacitors make the development board stable.
Software introduction:It communicates with the external system through the TTL level serial port. By default, it can directly communicate with the 5V system without level matching. When communicating with a 3.3V system or a 2.85V system, you need to do some processing on the hardware.The communication interface (command) is an AT command, that is, the control module realizes the function completely by the AT command, for example, the control module dials the phone to use ATD*******; (* is the other party's phone number)
