Slide Switch Wires

Prepare a set of two wires about 3.5inches (9cm) in length.

Using wire strippers, remove a bit of insulation from the tips of each wire.

Tin the exposed wire by applying a bit of solder to them.

This will help prevent the strands of wire from fraying.

Prep the Slide Switch

Snip off one of the leads on the slide switch, either the far left or right but not the middle. Then trim the two remaining leads short, about half their length.

Solder Wires

Solder the two wires to each of the leads on the slide switch.

A pair of helping hands can assist while soldering wires in place.

Connect Switch to Doubler FeatherWing

Solder one wire to a ground pin on the Doubler FeatherWing.

Then, solder the remaining wire to the EN (enable) pin.

Soldered Switch

Double check the wires from the slider have been soldered to the correct pins on the Doubler FeatherWing.

Switch Power Test

Test the slide switch by connecting the Feather RP2040 PropMaker to the Doubler FeatherWing.

Install 3x AA batteries into the AA battery holder. 

Plug in the cable from the AA battery pack. Ensure the built-in switch is on the ON position.

Use the slide switch to power on the Feather.

The Feather on-board NeoPixel LED should light up indicating it is getting power.

Then use the slide switch to power off the Feather.
