Hexy drops bluetooth and/or resets when moving

Hexy needs two power sources when running without the USB cable. One for the motors, and one for the logic.

Running with motor power only may work, but only until the motors start drawing too much power and crash the logic. 

Use a separate battery pack for the logic power in on the Serovotr32 board, and this should stop happening.
