I soldered mPCIe connector, but R11e-LoRa8 requires USB lines. Traces for USB lines seems to be hanging in the air. Having board with lte/gnss SMAs UP, just below the quecktel modem there are 2 6pin ICs. Between them there are 2 resistors (really small ones) with pads that allow to solder them horizontally or vertically - like [.:]. That connects USB to quecktel modem OR mPCIe connector. So.. easy way is to change resistors position. I checked that and LoRa card works fine, but LTE/GNSS functionality is lost.
I wonder if anyone have knot version with LoRa and is able to provide a detailed photo of both sides of PCB with card removed from slot. That would help a lot. I suspect there is a difference in CPU, or... some kind of USB hub is added somewhere to have LoRa and LTE working at the same time.
Also... to those 2 ICs external USB is connected - they are some kind of switch, so when You connect something to USB BG77 modem is disconnected from CPU USB lines.
