OctoDriver 8A Dual Motor Controller
The problem is:
- A lot of the inexpensive motor controllers are too meager to control anything but the most dinky motors. ladyada's Arduino shield only does 600mA continuous, 1.1A peak.
- The beefier controllers either:
- are really expensive (Pololu's DMC 01 can do 13 amps, but it's $100), or
- only control a single motor, or
- have complicated control schemes
So I've been on the lookout for a medium power, inexpensive, and easy to control circuit - I was flipping through starlino's website and I spotted exactly what I was looking for. He calls the circuit the 'OctoDriver', it combines 2 h-bridges to provide 8 amps peak, 4 amps continuous to each motor and with 4 chips, you can control 2 motors. I asked him if I could put it on a PCB, and he thought it was a great idea. I couldn't think of a better name, so I call my version "The OctoDriver".
You can find out more, pick it up, download files, etc, on the project page. I also did a pretty detailed howto. And like all the other Prop Platform Modules I've done, layout files are available under the MIT license.
What do you think?
