Gboard 800 SIM800 GSM GPRS Bluetooth Module Board For Arduino Starter

Description of product


Gboard 800 is a unique Arduino board which features a SIM800 GSM/GPRS/BT module, an XBee socket, nRF24L01+ module interface and an ATMega328P controller. This board can be added 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 800 can be used as a GSM/GPRS data transfer or wireless communication project development platform. Gboard supports wide range power supply and Micro SD for mass storage. There are some 3pin electronic brick/ sensor brick interface breakout on board, which offers 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.


  1. Gboard 800 has a micro USB connector only for debugging or firmware uploading.
  2. When you upload sketch to Gboard, please choose the board Arduino Duemilanove w/ ATmega328.
  3. The bootloarder file is ATmegaBOOT_168_atmega328.hex, you can find it in the directory arduino\hardware\arduino\bootloaders\atmega
  4. 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.

Attention: You can power the board through either the DC jack or the battery socket but NOT both at the same time. There is no Li-ion battery charger circuit on this board.
