This is for version 1.0-a/b/c. Version 1.1 has dedicated pins.

Power

Connect a LED to 5v with a resistor rated for your LED.

Activity

There are a few options, but none would be considered easy.

Use the latest firmware Directly connect to PA0

If you are on the latest firmware you can use the same pin, PA0 as 1.1 does, you will have to solder it yourself.

Remove existing LED

Remove the existing PC13 led and solder on your own, not recommended, but works.

Recommend LED and Resistors
