Q: Is arduino due or mega fast ?

Asked by Samson777 on 2019-01-07 12:47:19

fweinrebe Define fast? The Due is faster than the Mega because it uses an ARM processor. However the Due works with 3.3V logic where the Mega uses 5V as well as 3.3V.

fweinrebe 0. You will need a seperate driver board that can be driven by the Arduino. Depending on how many motors can be driven by the Arduino depends on the design. You cannot drive a stepper directly from an Arduino.
