This a simple breakout PCB for our [4x4 silicone button pads](https://www.sparkfun.com/products/7835). Each LED and button can brought out to the side connectors. The connectors are soldered to the back side of the PCB. We recommend trimming the connector leads on the button side as short as possible to reduce the deflection of the pad.

Now with footprints for diodes! Use the super cheap 1N4148 through-hole diodes. These can be used to [isolate the switches](http://www.dribin.org/dave/keyboard/one_html/) to make for a bit easier decoding.
