      Raspberry PI GSM Add-on is customized for Raspberry Pi interface based on SIM900 quad-band GSM/GPRS module. AT commands can be sent via the serial port on Raspberry Pi, thus functions such as dialing and answering calls, sending and receiving messages and surfing on line can be realized. Moreover, the module supports powering-on and resetting via software.

      Features

      • Quad-Band 850/ 900/ 1800/ 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

      Indicators

      • PWR

      Power: When there is normal supply to the board, the indicator keeps on.

      • STATUS

      SIM900 status: When SIM900 works normally, the indicator keeps on.

      • NET

      SIM900 network status: used to indicate network status, the working status of the indicator is as below:

      Network indicator status  SIM900 working status
      OFF SIM900 does not work
      64ms on/800ms off SIM900 does not find network
      64ms on/3000ms off  SIM900 registers the network
      64ms on/300ms off  GPRS communicates

      Keys

      • SIM900-PWRKEY

      SIM900 powering-on key: Keep pressing the key for more than 1 second, SIM900 will be powered on; keep pressing the key for more than 1 second after the board is powered on, SIM900 will be powered off.

      • SIM900-RST

      SIM900 resetting key: press the key, SIM900 will be reset.

      Note

      The module does not support hot swapping.

      Packing List

      • Raspberry PI GSM Add-on x 1
      • Antenna x 1
