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 |
