The Duets are Open Hardware and all hardware source files are available on Github.
Powerful 32 Bit Processor
Dedicated ethernet module.
Super quiet TMC2660 stepper drivers, up to 256 microstepping.
High speed uSD card and support for a second external SD card if required.
This is the latest PCB revision of the Duet 2 Ethernet, v1.04. The Duet 2 Ethernet is an advanced 32 bit electronics board for the control of 3D printers and other CNC machines. It has the same features as the Duet 2 Wifi, other than providing ethernet connectivity rather than Wifi. Similar to the Duet 2 Wifi, Duet 2 Ethernet can have Thermistors connected directly.
Item Specifics 1 - Duet 2 Ethernet Size: 3.92" x 4.92" Processor: ATSAM4E8E - 120MHz ARM Cortex M4F, 512Kb flash, 128Kb RAM, hardware floating point (single precision), DMA, 2Kb cache Stepper drivers: Up to 2.4A peak current Heater outputs: Bed heater up to 18A, 2 x extruder heater up to 6A each Input power voltage: 11V to 25V Inputs/Outputs: STP pins are 8V-tolerant on revision 1.04 and later, Z Probe IN pin is 30V-tolerant in revision 1.04 and later Fuses: 15A for bed, 7.5A for stepper drivers and extruder heaters, 1A for fans. 5V current limit: 2.0A total on 5V and 3.3v, including the internal current consumption (around 200-300mA), any PanelDue or other display, and any endstops/Z probes that draw significant power. Expandable up to 7 extruders with Firmware support for mixing nozzles and remapping axes to use high power external drivers. Support for the PanelDue: a full color graphic touch screen Support for DC42’s IR Z probe and the Duet3D Smart Effector for delta printers.
