Duet 3 Expansion Board 1XD v1.1

The Duet 3 Expansion 1XD is a CAN-FD connected expansion board for the Duet 3 Mainboard that provides connection to an external stepper driver and associated peripherals. It has standard Duet 3 RJ11 connectors for daisy-chaining the CAN-FD bus and accepts up to 48V to allow sharing power supplies with stepper drivers up to 48V.
