HGLRC Soter FPV Drone Buzzer
If you have ever spent hours stomping around in long grass, or even worse, actually lost a drone, this thing sells itself.
It's loud and it flashes if your battery disconnects or you're been hunting for over 30 minutes. It's tiny so it will fit in the tightest builds. It's got it's own battery backup so it works even if you crash hard and eject your lipo. And you can even wire it up to function as a standard buzzer that you can also trigger with a switch on your radio. Everything you need to have the best chance of getting your quad back.
Input voltage: 5V - keeps its battery topped up every time you fly.
Size:22mm x 12mm x12mm
