      Or can you only connect to DUET 2? Is there a separate duet 3 expansion board?

        duet 2 expansion board is not compatible with duet 3.

        duet3 uses can-bus for expansion
        duet 3 expansion board is here https://www.duet3d.com/Duet3Expansion3HC

          as above, but there are also the 1LC tool board and for weird custom stuff you can also use the development board linked below. dc42 has written a bootloader and firmware for it to act as an expansion board
