Indicators

  • PWR

Power indicator：Normally ON indicates normal power supply to Gboard Pro.

  • Status

Status indicator：Normally ON indicates SIM900 already powered on.

  • NET

Network indicator：OFF indicates SIM900 does not work; ON for 64ms / OFF for 800ms indicates SIM900 did not find the network; ON for 64ms / OFF for 3000ms indicates SIM900 registered on the network; ON for 64ms / OFF for 300ms indicates GPRS communication.

Buttons

  • Reset

ATmega2560 reset button：press the button to reset ATmega2560

  • Sim_rst

SIM900 reset button：press the button to reset SIM900

  • sim_pwr

SIM900 power button： if SIM900 is powered off, it will be powered on by keeping pressing the button (for more than 500ms); if SIM900 is powered on, it will be powered off by keeping pressing the button (for more than 500ms).

SIM900 power supply and reset connection

In Gboard Pro，power and reset buttons of SIM900 can be operated via software I/O pins, and the connection of pins is shown as below:

Arduino pin SIM900 pin Enable
D46 PWR High level Active
D47 RESET High level Active

Note: when you use Gboard pro, you must firstly connect with external power, then Foca. And before that you have to switch Foca to 3.3V, otherwise the LDO chip will be easily burnt.
