Easy to use and works great with Arduino or Wemos (ESP-8266) projects
This unit makes it easy to build your own smart home projects. The relay module just needs to be connected to the 5volt and ground on your micro-controller and one data pin.The relay has an isolated connection for the output, so you can use a different voltage if desired.I use these to "upgrade" inexpensive holiday decorations to eliminate having batteries. Plus, now I can control them from my Home Assistant controller.Easy project, quick return on investment.

Relay is great. Wires are so so.
The relay works perfectly and the connections are well marked. 5v comes in, 110v comes out based on the signal wire. The only issue is with the colored wire terminals. The first time they are installed the fit is tight, which is fine. If they are removed and reinstalled, then the fit is sloppy. Don’t know if this is a problem with all assorted wire packs.
