I have used servomotors from a developper kit (with EZ B 4) on a small robot and it works OK.
Now I want to use GM9 motoreductors (Solarbotics) instead.
So a got an EZ B H-bridge and noted connections used for Roli.
But I suppose that I have to add some protections between the EZB4 and the H bridge ?
Or elsewhere, so that no dammage happens . For EZB4 or H bridge.
What is necessary?
Thanks to help a beginner.
