Overview
Gboard Pro 800 is a unique Arduino mainboard with SIM800 GSM / GPRS module, XBee socket, nRF24L01 + module interface, micro SD card interface, ITDB02 parallel LCD module interface, electronic brick interface and ATmega2560 chips, which can achieve wireless control via XBee, nRF24L01 + or GSM / GPRS with functions covering from smart home to remote control of robots to meet various needs of different projects.
Note:
- 1. There is a USB connector on the board for debugging or firmware uploading to SIM800 module only.
- 2. The serial interface (bootloader connection) is 3.3v, not the typical 5v as on many Arduino boards - anyone using an alternative to the Foca board must take note not to risk damage.

Hardware
Note:
- Baterry Socket: you can connect a Li-ion battery onto the socket to power the board up instead of DC external power supply, the input voltage is from 3.4V~4.4V.
- Debug Port: debugging interface for SIM800 that you can upgrade firmware and debug software.
Indicators
1.PWR
- Power indicator：Normally ON indicates normal power supply to Gboard Pro 800.
2.Status
- Status indicator：Normally ON indicates SIM800 already powered on.
3.NET
- Network indicator：OFF indicates SIM800 does not work; ON for 64ms / OFF for 800ms indicates SIM800 did not find the network; ON for 64ms / OFF for 3000ms indicates SIM800 registered on the network; ON for 64ms / OFF for 300ms indicates GPRS communication.
Buttons
1.Reset
- ATmega2560 reset button：press the button to reset ATmega2560。
2.Sim_rst
- SIM800 reset button：press the button to reset SIM800。
3.Sim_pwr
- SIM800 power button： if SIM800 is powered off, it will be powered on by keeping pressing the button (for more than 1s); if SIM800 is powered on, it will be powered off by keeping pressing the button (for more than 1s).
