SIM808 GPRS/GSM+GPS Shield is a GSM and GPS two-in-one function module. It is based on the latest GSM/GPS 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. It has standard 4-pole TRRS headphone jack so that you can use any 'Android' or 'iPhone'-compatible headset with a mic. Also breakouts for external 32Ω speaker and electret mic if you don't want to use a headphone This module can do just about everything, like make and receive voice calls using a headset or an external 32Ω speaker+electret microphone, send and receive SMS messages or send and receive GPRS data (TCP/IP, HTTP, etc.). Now we has developed a new function for this board, it's become a GSM/GPS/Bluetooth three-in-one function module now. We improve our versions by upgrading bluetooth firmware. The new AT command for bluetooth also has been upgraded in the wiki. And if you want to update your old version sim808 shield, we also provide tutorial and component / antenna that you need. Features Controlled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands) Integrated GPS/CNSS Supports 3.0V to 5.0V logic level Low power consumption, 1mA in sleep mode Supports GPS NMEA protocol Standard Micro SIM Card Compatible with Arduino Uno, Arduino Leonardo, Arduino Mega Powered via Arduino USB connection or Arduino external power supply. Communicates with Arduino via UART-TTL and digital input/output.
