Having a little GPIO development board is extremely handy when building I/O projects for the Raspberry Pi.
In a previous article on my blog, I demonstrated how to build your own testing/development board from scratch:

However, since then, I learned about this kit from Gordon's blog:
Having a ready made kit with all the necessary components and a printed circuity board certainly lowers the barrier to entry and the complexity level. I have published a new article with detailed instructions on how to assemble this kit and have illustrated the wiring and pinouts for the buttons and LEDs in relation to the P1 header, Rev 1 GPIO pins, Rev 2 GPIO pins, and the WiringPi/Pi4J GPIO pin numbering scheme.
