For input voltage, the SB uses:

• 5V USB input (only for powering ESP32 and components)
• 12V Barrel Jack

For power circuit protection, need a way to switch between power supplies.

• Will use P-channel MOSFET for switching the 12V power off if 5V USB is present.

• For LED power, AMS1117 can not supply the required 4 Amps of current for all LEDs.
• Instead, using the AZ1084CD chip which can provide up to 5 Amps
