The external 4G modem extension for Andino boards is connected via USB. Using an LTE connection it can be used for high speed data transmission at a speed of up to 300 Mbit/s. It can also be used to send and receive SMS messages. Since, like our Andino boards, it is also DIN-Rail mountable, it can simply be mounted next to the device in question.
