I was already somewhat confused about your request as I never had heard of
amplifiers for motor power circuits. I thought you had something exotic laying around.
In that case as I said: I don't there there exists something like an amplifier for a motor driver.
But this is big forum so it may well be that somebody contradicts me.
I would also think that anything you buy will be more complicated to get connected and working
then soldering some wires on a Gertbot.
