Description
The module working withArduino,Raspberry Pi (version 3B+, 3B, 2B, B+ and A+)andthe BeagleBone Black, which enables communication in the standard of GSM, LTE. It allows forvoice calls, sending SMS messages. The better signal and accuracy is provided bythe GNSS modulewith support forGPS and GLONASS satellites. On the board are: connector forSIM card, powering module for battery LiPol andRESET button. It has connectors ofu.FL antennas for GSM and GNSS. The module supports GNSS antenna - active and passive.
The distribution of elements on the u-uGSM shield board.
