3pcs DC12V 10A 1CH 433MHz Wireless Relay RF Remote Control Switch Receiver Board
A part of the review has been auto-translated.
Super. Are also compatible with various 433Mhz transmitters. 3 switching modes possible.
I had already purchased 2 of these a few years ago. The presentation may not be top notch, they seem superficially assembled, but they are sturdy and work great. I've been using it for four years now.
I use this device with the Sonoff bridge. I have it controlling a siren. works brilliantly!
Very useful for remote control of equipment with the respective command
He arrived very quickly. It works according to the description.

Good product. Fast delivery. Pay attention for reset of the code. The procedure reported in description is wrong. The correct procedure is: Put the receiver in learning mode and press the learn button 8 times
