SIM808 GPS/GPRS/GSM Shield
Module interface and precautions:
1. Occupied pins: D0, D1, D12, the digital pin "D12" is connected to SIM808 module power GPIO. It can be used as SIM808 module on / off control.
2. SIM808 onboard MIC and 3.5mm SIM808 microphone are using the same MIC channel, when you plugin your microphone, the onboard MIC will be
automatically disconnected.
3. Boot switch button SIM808 module switch, shortpress 1s to start SIM808 , longpress 3s turn it off.
4. LED "ON" SIM808 power indicator, only when you connect an external power, the module can work properly.
5. Net GSM signal indicator
1. Fast Flash: Search Network
2. Slow flash (3s once): network registration complete
6. Function switch
1. None Vacant SIM808 serial pin to download the sketch, please dial to here.
2. USB_DBG When the expansion board plugged on the Arduino, dial to here to make SIM808 communicate with PC to make a debug (AT debugging).
3. Arduino When the expansion board plugged on the Arduino, dial to here to make SIM808 communicate with Arduino.
