3 Ways to power an Arduino Board - Do you know them?

This video tutorial discusses three methods to power an Arduino board: using the VN pin, DC Jack, and USB cable. Each method has specific characteristics and limitations. The DC Jack requires a voltage range of 7-12 volts and includes a diode for reverse polarity protection. The VN pin is similar but lacks reverse polarity protection. The USB port provides a regulated 5V supply and includes a thermal Poly fuse for current protection. The tutorial also highlights the importance of current management to prevent damage to the Arduino board.
