Overview
Gboard is a unique Arduino board which features a SIM900 GSM/GPRS module, an XBee socket, nRF24L01+ module interface and an ATMega328P controller. This board will add wireless XBee / nRF24L01+ control as well as GSM/GPRS connectivity to your projects. It’s great for anything from home automation to robot control. The possibilities are endless!
Gboard can be used as a GSM/GPRS data transfer or wireless communication project development platform. Gboard support wide range power supply and Micro SD for mass storage. There are some 3pin electronic brick/ sensor brick interface breakout on board, it offer an easy way for a quick prototyping. The board requires FTDI basic board to upload sketch, you can use our Foca board to do it. Gboard can be powered by a mini USB, power Jack.

UART Setting Jumpers
The SIM900 module and XBee module communicate to ATMega328 through UART. They cannot be used with the same port at the same time, so there are two UART setting jumpers to configure the UART communication. The figure of UART setting jumpers is as below.

D0 and D1 are hardware UART ports of Arduino. D2 and D3 are digital GPIO of Arduino. There are two configurations to set the UART communication.
