Frequently asked questions
What is the price of DC Power Adapter 5V 1A (2.1mm Barrel Jack) in Egypt?

Can I power an Arduino Uno through this adapter's barrel jack?
Not reliably. The Uno's barrel jack expects roughly 7-12 V, and a 5 V adapter is below the on-board regulator's minimum input. To power a 5 V board or module, feed 5 V and GND to its 5V and GND pins, after confirming the polarity.
How do I check the polarity of the plug?
The listing does not state the polarity of the plug. Check the marking on the adapter body, or measure the output with a multimeter before connecting it to your circuit, because reversed polarity can damage the connected device.
