Hi I made some research about your idea and I ready to start. I found a really beautiful board with Ethernet and a lot of I/Os. It’s a Nucleo Board really easy to find, really cheap (around 25 euros)

It’s based on STMF7 (really close as STMF4)
It could be a really good base to create a powerful parametric io expander. If other people want to help us it could be really efficient to have the same base easily available and cheap with integrated Ethernet interface.
