New SIM900 Arduino SIM900 GPRS GSM Shield Development Board Module Wit

详情

GPRS Shield  EFCom is an ultra compact and reliable wireless module. This GPRS Shield is compatible with all boards which have the same form factor (and pinout) as a standard Arduino Board. EFCom is base on SIM**0 4 Frequency GPRS module.

The GPRS Shield is configured and controlled via its UART using simple AT commands. Just plug this shield on the Arduino/ Lseeduino board, you could easily use AT command to control EFCom Shild. You can use the 2 jumper blocks to connect the SIM**0 URAT post to any pins within D*-D3(for Hardware/Software serial port). There is a switch on board , you can use it to select the connection of the UART port or Debug port , even be set on on Arduino, but by the switch and jumper block, the SIM**0 can be connected to PC via FT**3RL.

The shield allows you to achieve this via any of the three methods:

• Short Message Service

• Audio

• GPRS

We have layout of all of the SIM**0\' pins to the 2.*4 standard pitch. Not just the UART port and debug port\'s layout. The super capacitor power supply for the RTC. The RTC can work more than 1 days by the power supply of super capacitor. So the SIM**0 can keep the time and day when power off.

Feature

• Fully compatible with Arduino / Freaduino and Mega.
  Free serial port connecting, you can select Hardware Serial port(D0/D1) control or Software Serial port(D2/D3) control it.

• SIM**0 all pins breakout. Not just the UART port and debug port be layout, but also all pins on SIM**0 be layout to the 2.*4 standard pitch.
  Super capacitor power supply for the RTC.
  EFCom not only can use the button for power on , but also can use the digital pin of Arduino to power on and reset the SIM**0 module.
