Overview

IM150720001-Raspberry PI GSM SIM800 Add-on V2.0 (8).jpg

Raspberry PI SIM800 GSM/GPRS Add-on V2.0 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.

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

Keys

  • PWRKEY

SIM800 powering-on key: Keep pressing the key for more than 1 second, SIM800 will be powered on; keep pressing the key for more than 1 second after the board is powered on, SIM800 will be powered off.

  • RST

SIM800 resetting key: press the key, SIM800 will be reset.

Extension

  • External POWER IN

If SIM800 will drop off while working, please connect a external at least 5V/2A power supply to this micro usb.

  • Upgrade Port

This is only for upgrading firmware of SIM800.

Note

The module does not support hot swapping.
