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 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.

Specifications

PCB size 131.0mm X 68.8mm X 1.6mm
Supply voltage 7~23V DC
Operating voltage 3.3V DC
Microprocessor ATmega2560
Indicators PWR，NET，Status，Test
Communication interfaces XBee，nRF24L01+，UART，IIC，ITDB02 LCD，micro SD

Electrical Characteristics

Parameter Min. Typical Max. Unit
Supply voltage 7 - 23 VDC
Input high voltage VH 3 3.3 3.6 V
Input low voltage -0.3 0 0.5 V
Average Current consumption - 100 500 mA
Peak Current consumption - - 2 A

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.

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).
