Micro Warning Sound Module Beeper

Very small "sound module" with a real speaker. Originally it was designed as an acoustic back-up warning beeper. Now it is also available as horn or 5-tone melody fanfare. 
It is controlled either by connecting to a voltage (+/-) or by connecting to a channel on the receiver. The back-up warning beeper is typically connected in parallel to the speed controller with a servo y-cable. It then is activated automatically when driving backwards. The horn and the fanfare react to control signals above the center point and thus can be activated with a free channel by a switch or button on the transmitter. 
The installed potentiometer allows to adjust the volume from "pleasantly silent" to "nerve wrecking loud". 
It can be easily mounted with the M5 thread and finds a place even in tight places.
