The Duet 3 Mini 5+ is Duet's latest Mainboard and is an evolution of the Duet 2 Maestro. It 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.
The Duet 3 Mini 5+ provides 5 on-board drivers and the normal complement of heaters, fans, IO, LCD etc. There are Wifi and Ethernet variants with the option of using an SBC for control in the same manner as the Duet 3 Mainboard 6HC. Expansion options include the CAN-FD bus. It also has a header for a two-driver expansion board.
