Buzzer

Buzzer for audio feedback.

Since RDDRONE-FMUK66 Rev. C, this connector is not found on the board anymore. The newer FMUs now have a 10 pin connector for the Pixhawk 4 GPS, which has a buzzer inside. There is also no separate buzzer is included in the HoverGames kit anymore.

The 2 pin buzzer connector is not found on newer versions of the RDDRONE-FMUK66! The GPS module includes a buzzer. Please refer to the GPS connector page.

Schematic

Building the buzzer

• This is a piezo buzzer attached to a two pin JST-GH type connector.

• Polarity is not critical.

The buzzer cable looks like the image above when completed.

It can be made quickly:

• 1x 2 pin JST-GH housing.

• 1x 6" JST-GH pre-terminated wire.

• 1x Piezo buzzer.

• Cut the 6" JST-GH pre-terminated wire in half.

• Strip 5mm off the cut ends of the JST-GH wire you just cut in half, and add tin using a soldering iron.

• Solder the JST-GH wire to the stripped and tinned Buzzer wires.

• Apply heatshrink over each of the solder joints.

• Poke the crimped end of the JST-GH wire into the two pin housing.

• The order does not matter, but for consistency the red buzzer wire should go to pin 1.
