الوصف

SIM808 GSM and GPS Shield

GSM+GPRS+GPS+BlueTooth in a single shield

Main features:

Quad-band 850/900/1800/1900MHz
SMS
FTP/HTTP, embedded TCP/UDP protocol
DTMF detection, Bluetooth 3.0 (optional), USB interface
The power interface supports 5V voltage input. When the voltage is 5V, 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.
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. We will give a detailed introduction in the user manual.
