Product description: DFRobot Shield NB-IoT / LTE / GNSS / GPRS / GPS SIM7070G - shield for Arduino - DFRobot DFR0572
Module cooperating with Arduino , which enables communication in the GSM and GPRS standards. It allows you to conduct voice calls, send SMS messages. It also has a built-in GPS and LTE module. The board has: a SIM card connector, a u.FL socket for mounting an external antenna . NB-IoT is a new field of the Internet of Things, which supports connection to a cellular network in the WAN network. The SIM7070G module used enables communication via the GPRS / LTE network, it also has a GPS module. There is a SIM card slot on the board, and the connection of subsequent Arduino Shields is possible thanks to the led-out connectors.
Arduino compatible product
