You can select the role of your module very easily with a switch built onto the board. Plug-&-play, this module only requires to plug the telemetry equipment in order to be used. Its USB connector will allow you to configure it easily through the U-Center software. Also, the integrated compass will offer your vehicle a more accurate positioning and make your heading sensing more efficient (with the module being used as rover on your vehicle). Its I2C port will also allow you to add various I2C compatible devices to your system. The board has 7 through-hole connectors where you can solder pin header, which make the module very modular.
