  • Duet 3 Mini 5+ Ethernet v1.02

The Duet 3 Mini 5+ balances value and performance, focused on small and medium size machines that do not need the high power output of the Duet 3 Mainboard 6HC. It provides 5 on board drivers and a full compliment of heaters, fans and IO along with support for a variety of screen options. There are Wifi and Ethernet variants, with the option of using a SBC (Single Board Computer, e.g. Raspberry Pi) for control in the same manner as other Duet 3 mainboards.

The overall aim with the Duet 3 series is to allow for maximum flexibility of machine design through highly capable main boards, expansion boards, smart tool boards and custom expansion modules. The flexibility of configuration and advanced features are enabled by innovative RepRapFirmware 3 running on the Duet 3 Mainboard and optionally DuetSoftwareFramework running on a single board computer.


Powerful 32 Bit Processor (ARM Cortex M4 @120Mhz).


Add two more TMC2209 stepper drivers using the Duet 3 Mini 2+ expansion board.
For much more expansion use the CAN-FD BUS for connecting multiple expansion boards and tools.


Both Wifi External Antenna and Ethernet versions.
Dedicated High speed bus to a single board computer (e.g. Raspberry Pi) for the user interface and plugins.

Stepper Drivers

5 Trinamic 2209 stepper drivers running at up to 1.4A RMS, 2A peak with firmware control of the full feature set including up to 256 microstepping, StallGuard 2 and StealthChop2.

High current outputs

3 High current PWM outputs of varying current capacities support a high current heated bed and 2 extruders.

Medium current outputs

4 Medium current outputs designed for 2 wire (x2) and 4 wire (x2) fans


7 IO ports for endstops, probes, filament monitors and other sensors. Inputs are 30V tolerant.

Temperature Measurement

3 thermistor/PT1000 inputs.
Support for two temperature daughterboards for up to 4 PT100 or thermocouple sensors.


11V to 25V.


Runs RepRapFirmware 3.x – Supports all common machine geometaries, easily configurarable for your specific machine requirements.
