LoRaWan Expansion Board Alternative?

Hey all,

I’ve been trying to research using LoRaWan with MangOH Red, but I’ve run into an issue with the two providers listed on ATIM. Yadom does not seem to be able to ship the extension board to the US, and Lextronic doesn’t seem to have the board anymore.

Are there any alternatives?

Use any LoRa board/module and just connect via a standard interface such as UART or SPI … ?
