These are the current v6.1 IOBoards based off the MiSTerFPGA reference design.
i. Fan socket is a 2 pin header which is compatible with my fans and case designs. If you want a JST or Molex type socket please let me know.
ii. You will need to use the brass spacers that came with the DE10 Nano. If you got a DE10 from me and didn’t receive the spacers, let me know.
