Re: Searching IO0 Pin

Some 30-pin boards like yours do not break out GPIO0. My 36-pin devkit board does, and it also breaks out the pins normally reserved for flash (but I don't understand any use for them). Some 38-pin boards have two extra ground pins that are useful. So I'm more careful when I buy now.
