I have LoRa-less KNOT, but I was just curious if this can be added. I soldered miniPCIe slot, but no success. A little investigation what is connected where, and the result is that modem and LR8 are using USB. CPU in KNOT has only one USB port, so it has to be switched. I discovered 2 very small resistors close to modem that can be used to route USB lines to modem or to miniPCIe slot. I re-soldered them, and then LR8 is working, but modem is not...
What You do when You have not enough USB ports? I use the HUB
I developed small one, and embedded into KNOT to connect botm - modem and miniPCIe slot at the same time. And.. it works
