GSM/GPRS Shield Expansion Board EFCom Wireless Module With Antenna Description: The GPRS Shield-EFCom expansion board is a serial GSM / GPRS wireless module. Arduino enthusiasts to quickly learn a GSM / GPRS mobile phone development, and can be applied to wireless development projects to the class, but also suitable for remote control development, such as wireless meter reading, smart appliances, ultra-long-range control.   EFCom compatible with all the Freaduino and standards the Arduin development board. EFCom is a 4-band GPRS / GSM module supports four standard band 850/900/1800/1900MHz, send SMS messages, phone calls, faxes, etc. all GPRS handsets have features. EFCom allows your very fast phone development process and the wireless development.   EFCom SIM900 is a patch type GSM / GPRS integrated single-chip, ARM926EJ-S core, build enthusiasts and learn to use the smallest integrated development environment.   The EFCom using AT commands through UART serial configuration settings only need to extend the board into Freaduino board, you will be able to easily control via AT commands EFCom make calls, send text messages... addition EFCom support LCD5110 display (default hair Bluetooth backlight, is inserted in EFCom effect diagram below) and serial keypad keyboard input.   The board set the hardware boot the Button Software boot (D10), hardware RestButton, software Rest (D9) allows use and arduino spiritual and match to meet various types of both hard boot or soft boot or the hard reset or soft restart DIY needs. The two jump take to D0-D3, you are excelent to choose EFCom Arduino communication: software serial port (jumper cap to D2, D3) or hardware serial port (D0, D1).   EFCom three operating modes: Short Message Service SMS service mode Audio music mode GPRS mode Features: Fully compatible the Arduino and Mega2560 development board series Serial communication, the freedom to choose hardware serial port (D0/D1) or software serial communication (D2/D3) and motherboard SIM900, all the IC set aside not only the UART, DEBUG mouth, all GPIO port and KEY PANEL interface Board super capacitor to ensure the RTC work Support both hardware and software switch machines, support for hardware and software restart 4 band 850/900/1800/1900 MHz   Specification: The GPRS Shield power supply 5V GPRS multi-slot class 10/8 GPRS mobile station class B Compliant to GSM phase 2/2 +  - Class 4 (2 W@850/900 MHz)  - Class 1 (1 W@1800/1900MHz) Weight: 3.4g Control via AT commands (GSM 07.07, 07.05 and SIMCOM enhanced AT Commands) SIM application toolkit Supply voltage range: 3.1 - 4.8V Low power consumption: 1.5mA (sleep mode) Operation temperature: -40 ° C to +85 ° C Note: Plug Freaduino / Arduino Main Board, in connection we 9V DC AC adapter.
