Dispositivo Arduino

I think you need a raspberry, 4g usb modem compatible with linux. What is entrada p2? you mean ps/2 for a card reader/keyboard?

Hi, can you give me details about your project, I advise you to use alternative adruino with other microcontrollers, adruino is a closed system is more for education and university projects.
