Feather Switch JST Cable
The slide switch and JST extension cable will need to be soldered to the Feather M4.
Insert the 12-pin and 16-pin headers into the pins on the Feather M4. A breadboard can be used to assist in soldering by holding the headers in place.
Installing Feather Switch
The slide switch can soldered to the prototyping area on the Feather M4. This will keep the slide switch secured to the Feather PCB.
The slide switch can be placed on the far end of the prototyping area on the Feather M4. This gives easy access to the switch. Solder the pins to the Feather. Mounting tack can help keep the body of the slide switch in place while soldering.
Solder JST Cable to Switch
Using wire cutters, trim the ends of the JST extension cable short. The voltage wire is soldered to the middle and either far left or right pin on the slide switch. The ground wire is tied together. Pieces of heat shrink tubing are used to insulate the exposed wire.
Connect Battery to Feather
The battery is connected to the JST connected that is wired to the slide switch. The female JST connector is plugged directly into the power port on the Feather M4.
