SIM800 Module GSM GPRS Expansion Board UART V2.3 Quad-Band 850/900/1800/1900 MHz 2G Network for Raspberry Pi Geekstory

Description: Raspberry PI GSM Add-on V2.3 is customized for Raspberry Pi interface based on SIM800 quad-band GSM/GPRS/BT 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. Feature Quad-Band 850/ 900/ 1800/ 1900 MHz GPRS multislot class 12 Operation temperature: -40°C to +85 °C Operation Level: Digital 3.3V DC Interface: UART Baud rate: 9600(default) Indicators PWR (Power): When there is normal supply to the board, the indicator keeps on. 8STATUS (SIM800 status): When SIM800 works normally, the indicator keeps on. NET (SIM800 network status): used to indicate network status, the working status of the indicator is as below: Status SIM800 behavior OFF SIM800 does not work 64ms on/800ms off SIM800 does not find network 64ms on/3000ms off SIM800 registers the network 64ms on/300ms off GPRS communicates Document link: http://wiki.iteadstudio.com/RPI_SIM800_GSM/GPRS_ADD-ON_V2.0 Package Included: 1 X SIM800 Module 1 X Antenna
