This is awesome. However, it looks like this is just a breakout board. So you are still connecting stuff directly to the broadcom ARM chip. Which means it would be pretty easy to damage it.

"GPIO voltage levels are 3.3 V and are not 5 V tolerant. There is no over-voltage protection on the board - the intention is that people interested in serious interfacing will use an external board with buffers, level conversion and analog I/O rather than soldering directly onto the main board." http://elinux.org/RPi_Low-level_peripherals
