Description

This clever and clean push button breakout board comes as a kit and provides an easy way to add 4 tactile switches to any breadboard project. The normally open momentarily closed switches are great for managing a microcontroller's general-purpose input/output (GPIO) pins. Each switch is independent of the others allowing some switches to be used to pull some GPIO pins low, while other switches can be used to pull some GPIO pins high.

Soldering Tips

The following steps will help make soldering and assembly go smoothly.

1. First, place all of the pin headers into a breadboard with the correct spacing to ensure the tops line up with the PCB holes.
2. Place the PCB into position on top of the pin headers and solder them in place, soldering opposing pins first to keep things lined up.
3. Before placing the switches on the PCB, tin one pad of each of the switch footprints on the PCB (upper right for example).
4. Place the first switch and reflow the previously tinned pad ensuring its lined up. Repeat for the other switches.
5. Finally, go back and finish soldering all of the pads of the remaining switches.
