Wired Connections

The STEMMA Speaker needs three wired connections. Reference the circuit diagram and follow the colored wired to properly connect the STEMMA speaker to the Circuit Playground Bluefruit.

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

Battery Toggle Switch

The 500mah battery is connected to a toggle switch via a 2-pin JST cable. The voltage (red) wire is connected in-line with the toggle switch. Use the middle pin and either the left or right pins. This allows the power to be turned on and off.
