I work for Gumstix and we’ve released 2 gateway development platforms built arround the RisingHF RHF0M301. One of them uses our own Overo Computer on Module and has 10/100 Ethernet. The other uses the Raspberry Pi Compute Module or CM3 with Ethernet over USB and includes a connector for a NimbeLink Skywire LTE modem.
Both of these boards also have kits available in our store that include DC adapter, rubber duck antenna USB A-microB cable and the RHF module. The Overo Conduit kit also includes an Overo AirSTORM-Y COM. For the RPCM kits, you’ll have to get a compute module from an R Pi distributor. Go to https://store.gumstix.com/catalogsearch/result/?q=Lora and see what we’ve got.
P.S. There’s another interesting option for the RPCM coming soon, if power over Ethernet is of interest. Stay tuned.
P.P.S. I used Protocase to design an enclosure for my Overo Conduit board. They do good work.
