I am considering building a router to connect to the local 5G network. For that I would need a board, and a 5G module, and of course they should work with OpenWRT (or Linux in general).
I am thinking of getting a SIMCOM SIM8200EA-M2. This is a Qualcom X55 based module which is supported by Linux.
I would also need a board though, and my usual goto board for this only supports MiniPCIe, whereas the 5G modules is an M2 module (in fact, all the modules I found were M2 form factor).
Any good suggestions for a system board with an M2 slot, a Ge port, preferably POE powered? I don't need any WiFI on it.
