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

Plug in the 3-wire JST-PH cable to the port on the STEMMA Speaker. Reference the circuit diagram and follow the colored wired to properly connect the STEMMA speaker to the CPX.

  • Black wire from STEMMA Speaker to GND on CPX
  • White wire from STEMMA Speaker to A0 on CPX
  • Red wire from STEMMA Speaker to VOUT on CPX

USB Power

The Circuit Playground Express can stay connected via USB power from either a 5V wall adapter or computer's hub. This allows the project to stay on as long as you want (nightlight mode anyone?). The project has a cutaway to accommodate for a USB cable.
