The RGB LED button needs six wired connections. To make the assembly more efficient, I used JST-PH cables with male and female connectors. This allows for quick connections. A 4-pin and 2-pin JST cable set can be used to connect the button the Adafruit Feather.
Solder Button Wires
The connections are labeled on the bottom of the button housing. Reference the labels and sort out which wire will be soldered to the pins. The polarity from the two JST-PH cables needs to match exactly. To make soldering easier, I tinned each of the pins with a bit of solder. A Panavise can secure the button in place while soldering.
