GPRS RESET
The GPRS/GSM protocol is always enabled as there are no switches that configure it.
the GPRS / GSM protocol uses the SPI pins of the equipment to be able to communicate and
the pin2 for the module reset.
If you want to use the SPI pins, you must indicate in the program that pin2 is always in High
position. In case of using the SPI, the GPRS / GSM communication can not be used.

Ardbox - Arduino I/Os 5V pins
The Ardbox has some of the Leonardo board pins available. These pins can be programmed
according to Arduino features such as I/Os operating at 5V or any additional features present
in the pins (for example I2C communication in pins SCL and SDA). As this pins are directly
connected to the Arduino Leonardo board they are not as well protect as the normal inputs.
These pins are mainly meant to be used as prototyping.

*IMPORTANT:
Do not connect the terminals in the chart above to voltages higher than 5V.
These terminals provide direct access to the Leonardo board.
A part from the switch configuration there are some special conditions depending on these 5V.
Now it is going to be shown the considerations to operate with these pins.
