5 years ago There is a "servo HAT" to control servos for the arm but to control the motors you need a way to convert pulse width to varying voltages. The RasPi will send out pulses with varying intervals. This signal should go through a "motor controller" which contains circuitry that will take the pulse widths and translate them to varying electrical output to drive the motors at different speeds. This seems very similar to the one I used ( https://www.amazon.com/Qunqi-Controller-Module-Stepper-Arduino/dp/B014KMHSW6/ref=asc_df_B014KMHSW6/?tag=hyprod-20&linkCode=df0&hvadid=167139094796&hvpos=1o4&hvnetw=g&hvrand=11931195071073478197&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010794&hvtargid=pla-306436938191&psc=1 )

I am working on a similar project but didn't see if you needed to do anything special for the voltage to the motors.
Can you share the hats you were using the power the motors. I'm trying with just a explorer phat but I'm missing something with the battery and how that was all wired up.
