I was wondering what is the max current you can draw from your Arduino 5V and Vin pins.
My initial purpose was to find the best way to power servos, but I came to get interested by the way an Arduino works in itself.
I know it depends on your powerv supply, and I’m interested by what happens when you power your Arduino via USB. Now most topics about USB are about plugging your Arduino to your computer, but my idea is to power my Arduino with a 5V 1A USB cellphone charger.
Question 1 : When you power an Arduino with a 5V 1A USB cellphone charger, is there a difference between Vin and 5V pins? Is there a little less voltage on the 5V pin ? (I’m locked down with no Arduino to check it by myself)
Question 2 : I guess that powering an Arduino with a 1A USB cellphone charger allows for more current than a regular PC USB port, but how much? How much from the Vin and how much from the 5V pin?
P.S. I use Unos, Nanos and Megas, so any information is welcome !
