Which motor control board

Mon Apr 08, 2019 4:51 pm

So I am working on a rPi buggy using the instructions provided on this website, but I am having trouble finding the motor control board that are shown in the pictures. Does it have to be the same as shown, or would something else work too (such as the adafruit crikit HAT)?

One of these?

Just bought two of those yesterday xD

Beware that these driver boards use 5v logic and the Pi uses 3v3 logic. You'll need a level shifter to use them.

I have used those - and many other - motor driver boards that need to run on 5V and worked fine from a 3v3 gpio signal.

The only exceptions are the rare cases where the control signals need. more than5-10ma
