Sorry, I know this question has been asked many times, but all of the research I have done is conflicting.
I'm using this external 5V 20A PSU to power my Arduino and Neopixels. https://www.amazon.ca/ALITOVE-Transformer-Adapter-Converter-Charger/dp/B07DN8YX8G/ref=sr_1_2?keywords=ws2812+external+supply&qid=1589928727&sr=8-2
I was just wondering if it is safe to power the Uno through the 5V pin. I've done a lot of research, and it seems that as long as I am using a regulated 5V PSU and I connect the + and - terminals to 5V and GND on the Arduino respectively, the Arduino will not be damaged. Could anyone confirm this?
I'm curious about the current - I read that the 5V pin draws a max of 200mA from the PSU, so does that mean the other 19.8A will be directed to my LED strip?
