Adding an audible locator to your model is a great way to track it in tall grass or at a distance. This buzzer is compatible with BMK E36+ and B1 Rx timers that feature dedicated buzzer pads.
It uses a small coil element and an internal circuit to generate a continuous, clear tone — ideal for finding models after flight.
🔌 Connecting the Buzzer
Since Summer 2023, BMK E36+ and B1 Rx timers have solder pads specifically for this buzzer:
-
Connect (+) pin of the buzzer to the
BZR+pad. -
Connect (–) pin to the
BZR–pad (or any ground pad). -
Note: E36+ timers only have
BZR+pad due to space limitations. Ground can be taken from any (-) pad.
