I see, I'm not super familiar. My extent of PCB design is a custom slimevr board for myself.

The solderable 16 byte ROM design is interesting, I could maybe see it being in some kind of debugger?

Oh, that's cool. I hadn't heard of slimevr before.

My use case for the diode ROM board is to take 4 binary input bits (16 possible combinations) and translate them into what segments of a 7-segment LED display should be lit or unlit, in order to display the corresponding hexadecimal digit (0-9, A-F). Like so:

Diode ROM in use

It could be used for any other case where you need to convert a 4-bit input into 16 possible 8-bit outputs. In theory you could use them in multiples for more address space, but I forgot to include an enable pin on the board to allow for that. Something to add to the next version.
