The M36 hub board is specially designed for use with 36 circular stepper motors (Nema14) and can be used on mini Stealthburner or other print heads using 36 motors. This board can be used with a variety of motherboards, especially our catalyst and BullAnt. With special connection cables, it can also be adapted to any other system using klipper.

M36 is divided into two versions, mainly because of the difference in motor driver chips. The normal version is TMC2209, used with Catalyst motherboard; the Lite version is GC6609, used with BullAnt motherboard.
