Circuit Diagram

This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. This diagrams was created using Fritzing software.

Wired Connections

The Prop-Maker FeatherWing is fitted on top of Adafruit Feather M4 Express via short female/male headers. The RGB LED metal pushbutton uses several connections that are wired to the FeatherWing. The speaker is connected via a molex pico blade connector. The battery uses a JST PH connection that plugs in directly to the Adafruit Feather.

On/Off Switch or Button

Tying the enable and ground pins on the Feather will essentially shut off the power – Use a 16mm pushbutton with on/off latch. If you'd like to keep the two buttons in the hilt as momentary push buttons, you can optionally solder a slide switch directly onto the Prop-Maker FeatherWing.

RGB LED Button Connections

  • SWITCH pin on Prop-Maker FeatherWing to signal on Switch
  • GND pin on Prop-Maker FeatherWing to ground on Switch 
  • RED pin on Prop-Maker FeatherWing to RGB LED red cathode
  • GREEN pin on Prop-Maker FeatherWing to RGB LED green cathode
  • BLUE pin on Prop-Maker FeatherWing to RGB LED blue cathode
  • V+ pin on Prop-Maker FeatherWing to RGB LED common anode

NeoPixel Connections

  • NEOPIX pin on Prop-Maker FeatherWing to Data-In on NeoPixel Strip
  • GND pin on Prop-Maker FeatherWing to GND on NeoPixel Strip
  • V+ pin on Prop-Maker FeatherWing to +5V on NeoPixel Strip

Powering

The Adafruit Feather M4 Express can be powered via USB or JST using a 3.7v lipo battery. In this project, a 4400mAh lipo battery is used. The lipo battery is rechargeable via the USB port on the Adafruit Feather.
