An open-source hardware design for a high-current H-bridge.
It's called Lazy H for two reasons. First, that sounds like a cattle brand, and I've branded myself more than once on overheated switching transistors. Second, I'm TERRIBLY LAZY. Rather than create the same thing over and over again, I'd rather design it once, test it until it works right, and then just use the one I designed over and over again. I drive motors and other high current loads enough to justify designing and building this, just so I never have to do it again.
