Topic: Pro Mini- OK to provide external 5V power AND power via USB/serial programmer? (Read 339 times) previous topic - next topic

With an Arduino Pro Mini, is there power management capabilities such that I can plug in my (powered) USB/Serial programmer while the mini is also getting external 5V power on the VCC pin? Or do I need to remove the external power source before plugging in the USB/serial programmer?

Thanks!
John
