The robot is a carpet rover with a Pololu Dual MC33926 Motor Driver Shield
for Arduino and an Arduino Zero.
The motors are the 6 V high-power, carbon brushes (HPCB) 1600 mA
I am basing this information on what I read in the Pololu Dual MC33926
Motor Driver Shield for Arduino section.
I want to use a Arduino Zero and it is a 3.3V Arduino.
In the section I am referring to is about the Shield being used with a
Due, (also 3.3V) it refers to using a diode to limit the voltage on pin A0
and A1 to 3.3 volts. (Remember the shield.) It could draw up to 3+ amps.
Your site says there isn't too much to worry about, but it it goes on to
say that it would be safer, and no worries, therefore the diodes.
Once again this section refers to the idea about the limiting the voltage
on A0 and A1 to 3.3V. These 2 pins are set up in the shield for using
I don't know where I would wire this given the schematics for the MC33926.
Where would I wire the diodes too.
