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.
