The code provided on the Github page does not compile. There are open issues on the Github page that have been active for over a year with no resolution. The only thing that really got resolved was when the user did it for them. Avoid doing this unless you want to debug someone else's code. Update: They changed their code and now it's compiling. However, after some tests with a multimeter, the board lets through less than half of the input voltage. If you have 6v motors you need to put 12v across the board for the motors to work and then things get hot. Good idea with LEDs, but generally avoid them. It's far from worth the hassle and frustration. Even if they gave them away for free, I wouldn't want that.
