I’m a newb to Arduino. I’d like to get an external power supply. Can someone paste a link to a Sparkfun product page of the power supply I should get? Thanks! Rob
Any one of these wall adapters should work to power your Arduino through the barrel jack adapter: https://www.sparkfun.com/search/results … t=products. If you aren’t using an Uno, double check the datasheet for your particular board for the recommended input voltage range.
