The GPRS SIM900 Shield for Raspberry Pi consists of two components: A GPRS Shield with SIM900 module, and the Raspberry Pi to Arduino Connection Bridge that contains an Arduino-style socket into which the GPRS Module will connect.
The picture shows these components mounted on a Raspberry Pi board for illustration only. The Raspberry Pi board is not included. The connection bridge can be used on original Raspberry Pi models, Raspberry Pi B+ and Raspberry Pi 2.
The GPRS Shield for Raspberry Pi provides GPRS/GSM connection for your Raspberry Pi. It includes the SIMCom SIM900 communication module. This module has a U.FL antenna connection. You will need to add an antenna in order to use this board. We offer a compatible antenna.
You can use the free arduPi library which allows you to use your Raspberry Pi with the same code used on an Arduino. To do so, the library implements conversion functions so that you can control all the I/O interfaces (I2C, SPI, UART, analog, digital) on the Raspberry Pi the same way as on an Arduino. See the user manual for details.

Important! Powering the board The Raspberry Pi may not by able to provide enough current for the module to work reliably. If your module goes down when it tries to connect to the network, use an external power supply (12V, 2A) on the shield. If you use a power supply with output smaller than 2A, you should add an extra capacitor for the power, e.g. a 220 µF electrolytic capacitor between 3.3V and GND.
See the User Manual for important settings required for different power options.
