Re: Maximum current draw through DIO port
J,
When you speak of LEDs, many of us naturally think an LED string. A single LED can be switched by the DIO through a switching transistor or other driver. If your LED can operate (actually produce light) at 4 ma, you can sink that much current as quoted by Frank above.
