Often get questions about the different ways to power Arduino (from PC, a power supply, a battery, etc.) and how to connect to our source of energy to our board.
As for Arduino Uno keep in mind that its core (ATmega328) operates at a voltage of between 4.5 and 5.5 volts (can be up to 6 volts, but I strongly advise against), while the maximum current that can pass (incoming or outgoing ) by a single pin it is 40 mA.
The maximum current that can switch between pin Vcc or Gnd is 200 mA (do the sum of the currents entering and leaving the pin).
Apart from the use of the USB cable, as an alternative power source we can also use the connector, the required voltage must be between 7 and 12 Volt and this product is for you but you can also use it to power another.
