Description
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.
Hardware
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.
| Description | UART Setting Jumpers Connection |
| Hardware UART to SIM900,Software UAR to Specific | ST D0(Hardware Rx of Arduino),SR D1(Hardware Tx of Arduino),XT D2(Software Rx/Tx of Arduino),XR D3(Software Rx/Tx of Arduino) |
| Software UART to SIM900,Hardware UART to Specific | XT D0(Hardware Rx of Arduino),XR D1(Hardware Tx of Arduino),ST D2(Software Rx/Tx of Arduino),SR D3(Software Rx/Tx of Arduino) |
Power and reset connection of SIM900
In the GBoard, the PWRKEY and RESET pins of SIM900 module connect to Arduino as list below.
| Arduino pin | SIM900 pin | Enable |
| D6 | PWR | High level Active |
| D7 | RESET | High level Active |
Software
With embedded bootloader, Gboard is easy to use by Arduino IDE through Foca series. ISP of Atmega328 is broke out for download firmware easily.
Note
The GBoard does not have a USB connection. So you need a USB/Serial adapter - we recommend the Foca FT232RL breakout board.

Hello!Price Value Quality
I like the flexibility of the UART settings jumpers, which allows you to configure combination of AVR pin (D0-D3) is used for XBee socket DIN/DOUT.
However, I would like to suggest an improve for the next revision of this board. Please make the Foca-socket (7x1-pin socket on the back) also use DIN/DOUT instead of hardwiring it to D0/D1 of the AVR. This way the UART jumpers gives you the same freedom when using the Foca serial adapter.
Thanks! (Posted on 3/30/13) - very good board Review by Andrejus

This is an excellent board to start with, however, you may find yourself out of the SRAM (only 2K available on 328P). It would be excellent, if this would have the ATMEGA 1280 - just like Arduino MEGA... This design actually more preferable than mega+SIM900 shield, as the shield uses the 5V supplied by Arduino - meaning SIM900 will never be able to get 3A from arduino board, but THIS specific GBOARD actually solves this issue - full 3A available to SIM900!!! - the only drawback is the smaller CPU...

This board is excellent and recommended.. only the library from the download link is not working for received the SMS.. another think for Pin D4 and D5 why not the pin is not on the board.. (Posted on 12/11/12)Quality Price Value - Excellent Review by Norasmadi

This board is excellent.. I just hack a few to do wireless programming.. only my problem is the library, because to make call is OK, send SMS is OK only when RECEIVED SMS.. it is not working.. please help?? (Posted on 12/8/12)Quality Price Value - It's very nice board Review by Vladimir

It's very nice product, but the black color make the board looks dirty. (Posted on 8/23/12)Value Quality Price - Awesome customer service Review by Thomas

The reason i am saying that, it's because i unfortunately came across the product issue, but later so, solved! I bought from this company a lot, but this was my first time to contact them, they replied promptly and helped me get it sorted out. I will definetely recommend ITEAD to my associates, my friends.......Value Quality Price
No need to worry about product problems if you buy from ITEAD! Judging from my expercience, they take customers satisfaction seriously!
