As per the diagram at
http://wiring.org.co/ioboard/index.html#100

At the bottom right, where the diagram says VCC, GND, GND, 7-13V+, my board is a little different. It has 9-15v printed by the right-most pin.

Not sure, but am I right in assuming that pin is connected to the external (non-USB) power supply, and that's why the voltage varies? So as corollary, it will only provide power when using a non-USB power supply?

(In either case, which power supply range should I shop for, 7-13v or 9-15v?)

I'm just checking because I'm unsure after reading the ioboard.html page.

Thanks for your knowledge!

Yes, that pin is directly connected to the external (non-USB) positive power supply terminal. 9-13V 1000mA center positive will be fine.
