1. provides two types of antenna interface, compatible with the needs of the situation. This product has been shipped came with antenna, antenna with cable, it is compatible with two interfaces.
2. SIM900 by jumper settings, from any connection to the Arduino D0 to D7 of the two pins, not just only use D0D1 hardware UART.
3. Debug toggle switch, you can set the SIM900 the DEBUG port to Arduino or connected to the PC via ATMEGA8U2 / FT232 Arduino on, carry on the debug.
4. Audio and microphone mouth leads.
5. SIM900 plurality of IO mouth leads, if necessary, after a pin can be connected using a Dupont line – specific reference pin schematics and datasheet.
6.3 status LEDs, and three buttons – one of the power on button can be achieved by software POWER ON SIM900 using the Arduino pin.
7. 3.3V and 5V automatic level compatible with 3.3V or 5V can be adaptively control board to support this type of 3.3V Chipkit leaf maple and other platform development board.
The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07.07, 07.05 and SIMCOM enhanced AT Commands). The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module (They are all 2V8 logic) present onboard.
