The Duet 3 Expansion Board 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 share power supplies with stepper drivers up to 48V.
This Duet 3 1XD V1.0 expansion board offers the following possibilities:
- ARM Cortex M0+ processor (48MHz).
- 5V differential Step, Dir and Enable outputs for an external stepper driver.
- Two medium current (2A max recommended) outputs on VIN voltage with PWM capability and built-in flyback diodes.
- One output at 5V level with PWM capability (max 3mA).
- Three digital inputs with permanent 27K pullup resistors, protected against overvoltage.
- One thermistor input (PT1000 sensor not recommended).
- RJ11 CAN In and CAN Out connectors for connection to the Duet 3 CAN-FD bus.
- VIN: 12V-48V.
