The Duet 3 Expansion Mini 2+ is specifically designed for the expansion header of the Duet 3 Mini 5+. It may be possible to use it with other mainboards but this is not supported. Includes connector kit.
It provides 2 x TMC 2209 stepper motors drivers with the same configurability as the 5 mounted on the Duet 3 Mini 5+:
