This module is a nice little relay switch controlled by a spare auxiliary channel on your receiver. Ideal for switching lights, sound, and any other auxiliary electrical items. When PWM duty is more than 1500us, the switch will turn on; when PWM duty is less than 1400us, the switch will turn off.
The module can read a pulse width that can range from 400 to 2600us. If the width of the pulse is more than 1800us, the MOSFET switch will close, if less than 1200us, the MOSFET switch will open.
The LED will fast blink 30A RC Controlled Switch: Large current, high reliability, supports high voltage receivers, compact size, lightweight. 18AWG silicone wires for power, super-soft silicone wires for the signal as well.
