You may need a little glue to keep the switch in place: hot glue or a dot of epoxy worked fine for us. Adafruit also place a 1N4148 signal diode in series with the switch, so you can create key-grid matrices without worrying about ghosted keys.\u003c\/p\u003e\n\u003cp\u003eEach breakout also has a single reverse-mount NeoPixel pointing up through the spot where many switches would have an LED to shine though. The input and output of the pixel are broken out so you can 'chain' these board together and control them as one NeoPixel strand.\u003c\/p\u003e\n\u003cp\u003eThere's plenty of flexibility for any kind of use, each board has the following pin out:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVDD (+)\u003c\/strong\u003e The power pin for the NeoPixel, provide 3 to 5VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGND (-)\u003c\/strong\u003e The ground power pin for the NeoPixel, connect to ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn (I)\u003c\/strong\u003e and \u003cstrong\u003eOut (O)\u003c\/strong\u003e The input and output to\/from the NeoPixel, for chaining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Anode (A)\u003c\/strong\u003e - The 'positive' side of the switch+diode.

If you're using a pull-down, connect this pin to your microcontroller.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThere's two rows of 5-pin contacts on a 0.1\" grid on both sides. Solder in both sides for mechanical stability, the two sides share the same pins except for one side is NeoPixel in and the opposite side has the out pin. For side-by-side wiring, we also have the cathode pin broken out on the sides, and another set of NeoPixel In\/Out pins.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note, each order comes with one assembled PCB and a small stick of break-off header.\u003c\/strong\u003e Soldering is required to attach the header for breadboard use.
