Here the photos of the Banggood JHE42B buzzer finder for quadcopers and drones and airplanes. It died without notice so I opened it to see what it contain and what could be the reason (you will see on the photo of the chip there is a small crater that shows a burst inside the chip so it is definitely dead). Inspection of the various item will follow. Banggood is selling interesting stuff but dies quite fast too and usually after the 6 month warranty. This drone finder buzzer JHE42 died after 7 month but has beed used maximum 10 times.
The buzzer jhe42b stopped working after 4 flights
