Duet 3 Expansion Board 1XD v1.0
CAN-FD connected expansion board for the Duet 3 Mainboard that provides connection to an external stepper driver and associated peripherals.
Processor: ARM Cortex M0+ processor running at 48MHz
Connectivity: 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.
IO: 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.
Firmware: RepRapFirmware 3.x
