Duet 3 Mini 5+ Wifi v1.02 - Motherboard for small 3D and CNC printers

Duet 3 Mini 5+ balances value and performance, is a board designed for small and medium-sized machines that do not need the high power output of the Duet 3 Mainboard 6HC. It provides 5 driver motors and the normal complement of heaters, fans, IO, LCDs, etc. Two Wifi and Ethernet variants are available, with the possibility of using an SBC (Single Board Computer, e.g., Raspberry Pi) for control in the same way as other Duet 3 motherboards. The overall goal of the Duet 3 series is to allow maximum flexibility in machine design through highly efficient main boards, expansion boards, and custom expansion modules. Configuration flexibility and advanced features are enabled by our innovative RepRapFirmware 3 running on the Duet 3 motherboard and our custom DuetSoftwareFramework running on a computer.

Here in summary are the main functions:
- Powerful 32-bit processor (ARM Cortex M4 at 120 Mhz).
- Two Wifi and Ethernet versions available
- Dedicated high-speed bus for communication with a computer (e.g.,Raspberry Pi) for user interface and plug-ins
- 5 driver stepper Trinamic 2209 running up to 1.4 A RMS, 2 A peak with firmware control of the entire feature set including up to 256 microstepping, StallGuard 2 and StealthChop2
- CAN-FD bus supporting the next generation of expansion boards Duet3D, smart tools and custom add-ons.
- 7 PWM outputs of different current capabilities support a high-current heated bed, 2 extruders and 4 fans.
- 7 IO ports for limit switches, probes, filament sensors and other sensors.
- 3 thermistor / PT1000 inputs and support for 2 PT100 or thermocouple inputs via optional expansions.
- Configure the printer and update firmware via the web interface.
- All common 3D printer geometries are supported.
- Support for a wide range of Z probes including the DC42's IR Z probe and the Duet3D Smart Effector for delta printers.
