FAQ

What are DM-J modules used for?

Finger, wrist and light arm axes — anywhere size and cost per axis matter more than peak accuracy. Common in hands, student builds and prototypes.

How are DM-J modules controlled?

Over CAN using MIT mode, with a compact matching controller. A good fit if you already run a MIT-mode stack.
