Works well, responds fast.Good circuit board layout for isolation of the relay load contacts and traces.I tested using RealTerm by sending on and off commands manually.I also used a PowerShell script I found with web search. Popular device lots of support.

Excellent! simple compact and easy to implement over serial. Board uses a CH340 usb driver. I am disappointed with no documentation or information provided with the device but its pretty simple to use. looking it up online i found it chats at 9600 baud, and responds to Turn On: A0 01 01 A2 and Turn Off: A0 01 00 A1. I did a quick test with python and it rand great. A little red power LED and a green relay light is available.

I've only just started using it, but it seems to work so far. The solder joints are pretty sloppy so we'll see how long it lasts.Since I can't include code to links to my Github, I've included an image of a simple Python script (relay.py) using PySerial to make this thing work.

I have tried two of these boards now, and they both stopped working after about a week. At first I thought it was just a problem with the first board I purchased, so I bought another one. When they fail, they first become flaky and you have to repeat the on or off commands multiple times. Then they ignore all commands totally and never work again.
