Genuine Duet 3 MB 6XD

Description

Genuine Duet 3 MB 6XD

The Duet 3 Mainboard 6XD is designed to allow interfacing with the most common external stepper and servo motor drivers using step and direction signals, with support for 6 external drivers. In addition it provides opto-isolated Input and Output connections for some of the GPIO functions to allow easier interfacing with PLC control systems.

Like the other Duet 3 mainboards it can be accessed directly over the network in stand alone mode (via the Ethernet port) or it has the option of using an SBC (Single Board Computer, e.g. Raspberry Pi) for control. Using the Duet 3 CAN-FD bus it is expandable with the range of Duet 3 expansion and tool boards.

• Processor: ATSAMV71Q20B. Alternatively the ATSAME70Q20B will be used. They are functionally equivalent in this design
• Processor features: 32-bit, 300MHz ARM Cortex M7, 1Mb flash, 384Kb RAM, hardware floating point (double precision), DMA, 32Kb cache
• Networking/Comms: 10BaseT/100BaseTX Ethernet, or via attached SBC; USB port; serial port; CAN-FD bus
• External Driver Support: 6 ports with step/direction/enable outputs, and fault inputs. Signalling is 5V single ended.
• High current outputs: 3 x 6A each
• Medium current output: 6 x PWM-controlled outputs, of which 3 support tacho input. Voltage selectable between VIN / 12V / external power, in 2 individually-fused banks. 1 x VIN-voltage, always-on output. 1 x 12V, always-on output.
• Thermistor/PT1000 inputs: 4, optimised for 100K thermistors and PT1000 sensors
• Inputs/Outputs: 9 on-board I/O connectors for endstop, filament monitor, Z probe, hobby servo, or PanelDue connection. Inputs are 30V-tolerant. 4 of the 9 pairs of IO also have alternative opto-isolated connectors.
• Power monitoring: VIN voltage monitoring allows for state save on power failure.12V regulator output voltage also monitored
• SD card interface: On-board high speed (25Mbytes/sec) SD card socket. External SD card socket (e.g. on attached PanelDue) also supported.
