Ghani Lawal- Power Sources: Battery, USB 1, USB 2
- Battery is the primary power source, for everything
- USB 1 is the secondary power source, will power everything except the motor drive
- USB 3 is the tertiary power source, only powers the Bluetooth module
- Will use a separate 3.3V regulator to power the Bluetooth module
- Will use "Diode power selector" - basically a priority OR gate between power source and regulators
- Schottky diodes for the Battery and USB 1, since batter has a much higher voltage than USB it will have priority over USB1
- "Regular" diode for USB 2, the larger voltage drop will give USB 1 a higher priority over USB 2
