I do not have a mini, but it looks like the spacing is such that you can solder a pin header in there and then use a ribbon connector to plug in. The other end can the be connected to Leds. Yes, I will not solder directly to the board, but use a header.
The header does provide both +3.3v with a load resister and gnd. See schematic.
I would use the lowest current draw led's I can get, as normally each led has it own load resister.

I THOUGHT I'd seen that somewhere !
I've got to go find it. It's not in my local 'collection'. Since my post may be relevant to a few boards (?) I'll leave it up for now.
