A small adjustable switching BEC for powering cameras, video transmitters, LED diodes and other electronics. The BEC supports input voltage 4.5–24V. The output voltage can be smoothly adjusted with a trimmer in the range of 0.8–17V, or you can choose one of the fixed values 1.8 / 2.5 / 3.3 / 5 / 9 / 12V by bridging pads on the bottom side of the board. Maximum current is 1.5A. The output can be turned on and off with the EN pin.
The input voltage must be higher than the output voltage. The module has no reverse polarity protection.
