Duet 3 Expansion 1XD is a CAN-FD connected expansion board for the Duet 3 motherboard that provides connection to an external stepper driver and associated peripherals. It has standard RJ11 connectors for CAN-FD bus connection and accepts up to 48 V to allow sharing of stepper driver power supplies up to 48 V
Here are the main functions at a glance:
- 48 MHz ARM Cortex M0 + processor
- 5V outputs Step, Dir and Enable for an external driver stepper (can be used in differential or single ended mode)
- Two medium-current (2A max recommended) VIN voltage outputs with PWM capability and built-in flyback diodes
- One 5 V output with PWM capability (3 mA max)
- Three digital inputs with permanent 27K pullup resistors, protected against overvoltage.
- One thermistor input (reduced accuracy compared to other Duet 3 boards, so PT1000 sensors are not recommended).
- RJ11 CAN In and CAN Out connectors for connection to Duet 3's CAN-FD bus.
- VIN: 12V-48V
