The K001 Humble Pi is a handy board that offers a compact and concise shield that fits perfectly on top of the Raspberry Pi.
The Humble PI allows for a place to add a voltage regulator, some capacitors and a DC socket. This will allow for you to have an add-on power source for projects that will require a little more juice. A few more handy features include pads in groups of three and power that is arranged down the middle.
