6.4 Power Supply
The Arduino Due can be powered in multiple ways:
USB Type-B port (Native port and Programming port).
Using an external voltage source connected to VIN pin, which has a recommended voltage range of 7-12 VCC.
The Power Jack: The Due can be powered using a DC power supply connected to the power jack, which accepts
a voltage range of 7 to 12 V.
It is essential to note that the Arduino Due operates at 3.3 V, so any external power source must be
regulated to this voltage level. Additionally, the power supply should be able to provide sufficient current
for the board's operation and any connected peripherals.
