JHE42B-S is a new version of a standalone buzzer with reduced size and weight, which is used to find a lost model in case of main power failure.

The power outputs (red and black) are connected to the quadcopter's 5V BEC, the green wire to the BUZZ-controller pin for manual control of the squeaker.
V2 version adds a second LED for status indication
