Sorry to bring this up again, but I found another shield that is super cheap and looks really good. Plus it will interface with my grove starter kit sensors! The only problem is I can not find a data sheet, so I don't know what the voltage loss is. When I click the links tab it just says "loading…" I was wondering if anybody knows about how much voltage it will lose.

Thanks,
Drew Davis

It's based on the L298, so it will have a high voltage drop.

I was looking through different motor control posts and I saw that you recommended this controller…

Would It work in my case?

Thanks,

Yes, the specs for that motor driver would work for you according to the link to your motors that you provided. This is the motor driver that I use. It's not a shield so you'll have to do a bit of wiring, but it's not bad. There are quite a few tutorials if you do a search, and someone wrote a library as well.

Thank you!


Do you know what the voltage loss is?

From the data sheet linked to on the Sparkfun page, it's 0.5V typical, 0.7V maximum @ 1A.
