Can the Duet Expansion Breakout Board be connected to DUET 3?

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

[Veti]

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
