Wave Sim808 GSM/GPS Shield + Antenna

The GSM/GPRS/GPS shield is an Arduino shield based on the Quad-band GSM/GPRS/GPS module SIM808. 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, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation. Also breakouts for external 32Ω speaker and 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 microphone, send and receive SMS messages or send and receive GPRS data (TCP/IP, HTTP, etc.).

  SEND MESSAGE

  Software serial multple serial test

 Receives from the hardware serial, sends to software serial.
 Receives from software serial, sends to hardware serial.

 The circuit:
 * RX is digital pin 10 (connect to TX of other device)
 * TX is digital pin 11 (connect to RX of other device)

 Note:
 Not all pins on the Mega and Mega 2560 support change interrupts,
 so only the following can be used for RX:
 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69

 Not all pins on the Leonardo support change interrupts,
 so only the following can be used for RX:
 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).
