Review on 📡 Raspberry Pi NB-IoT Cat-M (eMTC) GNSS HAT with LTE GPS External Antenna, SIM7080G, for Pi 4 3 2 Model B B+ Zero W WH, USB Interface UART. Supports GLONASS, BeiDou, Galileo. By XYGStudy by Jessie Drury

I like small size, good performance and good antennas. I spent extra time getting the GPS to work while the cellular data was active, and after the GPS turned on, the cellular data stopped working. What the documentation doesn't say: You can't use the typical gps on command and the nmea search command. Instead, use the command AT+SGNSCMD=1.0 and wait for a GPS frame. See the simcom help manual for more information. You can get them from waveshare (dot com).
