Any recommendations from where it would be easiest to order such board?
I'm based in Europe and would like to get one.

Is the board otherwise plug&play to an M.2 E-key slot or does it need
something special?

BTW in general we don't support distro kernels:

This means that board-2.bin is missing the board file for your device.
For AP devices like QCN9274 board files handling is difficult, usually
Device Tree is the only way to get automatic board file loading working.

Did you get any software with your the board? Do you know if the board
is calibrated or not?

Can you run:

find /lib/firmware/ath12k/ -type f | xargs md5sum

I do not know what these zst files are. And don't copy anything from
WCN7850 directory, the files are not compatible. The best is to run
'make install' within ath12k-firmware.git repository, manually fixing
files will end up into problems.
