Thanks for that. In the first picture you posted, to me it looked like a component was added next to the motor controller, but now I can see it was just the header pins you had soldered in for connections!
I was wondering if the current is still limited to 1.5 A. I pressume it will be, as from the data sheet it says it is internally overload protected. Does the chip need a heatsink though, when running with the extra voltage?
