Duet3D 1XD

Product description

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.


ARM Cortex M0+ processor running at 48MHz.


RJ11 CAN In and CAN Out connectors to connect to the Duet 3 CAN-FD bus.

External Stepper Driver Connection

5V differential Step, Dir and Enable outputs for an external stepper driver (can be used in differential or single ended mode).

Medium current outputs

Two medium-current (2A max recommended) outputs at VIN voltage with PWM capability and built-in flyback diodes.


One thermistor input (reduced accuracy compared to other Duet 3 boards, designed for motor temperature measurement).
One 5V-level output with PWM capability (3mA max).
Three digital inputs with permanent 27K pullup resistors, protected against over-voltage.
