So, I've made my own spin of this board. I swapped out the expensive buck converters with cheaper options (still from TI) and optimised the layout somewhat.
I also spaced the two halves of the PCB so they can be easily cut apart with
one of these. (Ignore the trace connecting the two sides, it's just to try to trick the PCB manufacturers into thinking it's not two separate designs....

)
The BOM file is such that it should be able to be dropped into JLCPCB for assembly, I
think... I haven't tried so let me know how you go...
It
should all just work (I made no major changes besides the DC-DC converters) so take this as a Beta version until verified by someone.

As for the displays, you can get them on Aliexpress, but JLCPCB has them in their catalogue for their assembly service too.
I plan to get a bunch made sometime soon-ish, so I'll report back once it's done.
