I have found one instance of someone connecting a Sixfab NVIDA Jetson Nano 4G/LTE Modem Kit to the Jetson Orin Nano using a Male to Male USB A cable. Wondering if there are any other options.
Suggestion:
You should buy the kit with a 5G module. I went for the RM500U-CNV.
Big Advantage: NO drivers whatsoever needed. The 5G module can act itself as a router and talks directly to the Ethernet NIC in the case. When using USB the modem can expose an USB CDC-ECM/NCM network interface which Linux can handle without additional drivers. The modem includes DNS, DHCP, and NAT services.
