Thanos, Tux is right, PWMing the motors at 50Hz is not a good idea. Measuring the voltage across the motors can be done using a voltmeter. Since the IOIO doesn't work now, I would advise you as a first step to disconnect as much as you can from it, plug it into a PC and see if the power LED turns on and if anything gets hot. Also, try powering it externally without USB and see if you have the power LED on. Send you schematic as an image and I'll review it for any possible errors. I don't know what to do with a .fzz file...
