A little reminder.
The boards come with the micro USB ports, for configuring the GPS modules, already assembled on the board.
There have been some of those ports that were not very well soldered from JLC.
If you connect to a gps with a proven, working usb cable, and a port does not open on the computer, you may need to resolder the small solder joints on the usb port.
Just reheat with soldering iron only.
