- 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.
