Product description
Low stock - we are expecting more stock towards the end of October 2024
The Duet 3 Expansion board is a CAN-FD connected, high current, full featured expansion board for the Duet 3 mainboards. Pair one of these expansion boards with a Duet 3 Mainboard 6HC, Duet 3 Mainboard 6XD or a Duet 3 Mini 5+ to control 3 high current stepper drivers, 3 high current loads, 6 fans and 6 IO channels. Further 3HC expansion boards, tool boards and 1XD expansion boards can be added to the CAN-FD bus if necessary to complete your machine design.
