Overview

IComsat .jpg

IComsat is a GSM/GPRS shield for Arduino and based on the SIM900 Quad-band GSM/GPRS module. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands), and fully compatible with Arduino / Iteaduino and Mega.

Features

  • Quad-Band 850/900/1800/1900MHz
  • GPRS multi-slot calss 10/8
  • GPRS mobile station class B
  • Compliant to GSM phase 2/2+
  • Class 4 (2W@850/900MHz)
  • Class 1 (1W@1800/1900MHz)
  • Control via commands (GSM 07.07, 07.05 and SIMCOM enhanced AT Commands)
  • Short message service
  • Free serial port selection
  • All SIM900 pins breakout
  • RTC supported with Super Cap
  • Power on/off and reset function supported by Arduino interface
