Due and Motor Control

Development Boards Arduino
1

Hello,

I have been playing with Arduino for a couple of months now. I now have an Arduino Due and I cannot use motor shields using the L293D. They take a logic supply voltage of at least 5V and the Due outputs 3.3V (from what I have heard). Along with that my shield does not have protection diodes and requires external protection diodes.

Simply, is there a shield that at least has the following criteria?

  • can control up to 4 DC motors

  • imbedded voltage level converter (for Due) or possibly another solution

  • protection diodes.

For testing I used the MotoMama (attached) with an UNO and everything looked great - but now I need more motors and using a Due brings some issues.

Does anyone know of a shield?

Thanks,

Danny

I couldn’t find anything on Google for a Due Motor shield. You could always design your own.

The Due is still new and will prolly be awhile before a dedicated motor shield is built for the Due simply because people are trying to understand the programming. Hell, there is only like 3 or 4 libraries out now. Only 2 libraries come with the 1.5 Arduino IDE.

Yeah I guess you are right, I am continuing to use my shield - it may work depending on your motors.
