Do not apply voltage to any I/O pin when power is not supplied to the board. it will damage the processor.
^^^ Just noticed that while reading the specs. As long as the clock and data lines coming out of the board don't get swapped with the +12 or +5 you shouldn't ever put some power back into the board.
Having said that, its much more robust that the PI. I've given a couple of my BBB's a bit of hell and they survived. However, the main reason for the cape is actually to buffer the uP GPIO. Worst case you'll blow up the buffer IC. I've actually hooked up pixels directly, and it works, but (a) its only 3.3v logic which makes it marginal for many pixel types, and (b) you need a bit more drive current that the GPIO will supply nicely..
