Hmmm... That's not really how electricity works. The motors and IOIO/phone are connected in parallel and both will potentially draw current at the same time. Your phone has no idea that the motors are running and/or what is the current budget. This design runs the risk of:
- Damaging the boost regulator on the charger/boost board. This is probably not very likely, as most sane regulators have over-current protection, but I haven't looked at this specific one. - More likely, you will see drops in the connection between the IOIO and the Android, as result of voltage dips caused by current spikes by the motors. And of course, you might get lucky and it will just work... If it doesn't, at least you know where to look for the problems. Good luck, and share your results!
