SIM808 GPRS/GSM+GPS Shield

SIM808 module is a GSM/GPS/BT three-in-one function module. It is based on the latest GSM/GPS/BT module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation. It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels. Besides, it supports A-GPS that available for indoor localization， and it also supports for Bluetooth 3.0.

The module is controlled by AT command via UART and supports 3.3V and 5V logical level.

This shield is built to directly work with Arduino

Application:

1. M2M (Machine 2 Machine) Application – To transfer control data using SMS or GPRS between two machines located at two different factories.
2. Remote control of appliances – Send SMS while you are at your office to turn on or off your washing machine at home.
3. Remote Weather station or a Wireless Sensor Network – Make it with [Crowduino v1.0|Crowduino v1.0] and create a sensor node capable of transferring sensor data (like from a weather station – temperature, humidity, etc.) to a web server
4. Vehicle Tracking System – Install GPRS+GSM+GPS Shield in your car and publish your location live on the internet. Can be used as an automotive burglar alarm.

Features:

1. Quad-band 850/900/1800/1900MHz
2. GPRS multi-slot class12 connectivity: max. 85.6kbps(down-load/up-load)
3. GPRS mobile station class B
4. Controlled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands)
5. Supports charging control for Li-Ion battery
6. Supports Real-Time Clock
7. Integrated GPS/CNSS and supports A-GPS
8. Low power consumption, 10mA in sleep mode
9. Supports GPS NMEA protocol
10. AT command operation, can support SMS, phone, GPRS data, GPS data is automatically output, embedded TCP protocol to support transparent mode and command mode, supports HTTP protocol to support DTMF decoding, support MMS, support recording function, etc.
11. Standard Micro SIM Card.
