Q: Can the digital pins output 5v if the board is just plugged in via USB?

theTobster500 yes, you can drive a 5V device from the 5V and GND pins just using USB power. you probably shouldn’t drive more than 1A out of it without a separate power supply though. i use WLED to drive an RGB strip from it and i could use it just fine with just the usb
