Overview

GPRS module.jpg

GPRS module is a breakout board and minimum system of SIM900 Quad-band/SIM900A Dual-band GSM/GPRS module. It can communicate with controllers via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). This module supports software power on and reset.

Features

  • Quad-Band 850/ 900/ 1800/ 1900 MHz
  • Dual-Band 900/ 1900 MHz
  • GPRS multi-slot class 10/8GPRS mobile station class B
  • Compliant to GSM phase 2/2+Class 4 (2 W @850/ 900 MHz)
  • Class 1 (1 W @ 1800/1900MHz)
  • Control via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands)
  • Low power consumption: 1.5mA(sleep mode)
  • Operation temperature: -40°C to +85 °C
