Doing research on the board requirements.
There can be lots of different uses of the serial expansion board and I don't feel this board should be rigid in any way.
DMX has a lot of variety. There are different standards, I'm finding DMX 512 to be the most popular on internet and even that uses many variants of XLR connectors.
I'm thinking of a modular setup with a base board having the VHDCI connector and 6 UART port headers spaced apart appropriately and a family of pluggable modules that connect to these headers and convert UART to interfaces like RS232, RS4xx, DMX 512 (uses XLR connector), GPIO header etc.
This looks more efficient in many ways - User can keep the same base board and keep plugging-in different modules depending on requirements.
