Alternative rs-485 module

[wallyllama]

I've come across a diiferent rs485 module labeled XY-017. T claims to be "stable" and or "reliable" and have a uart. Has any one tried them? All sellers I've found seem to use the same (probably google) tranlation, and there is no mention of the chip other than "imported". I'm guesing they mean not counterfeit, but are they max485 or other?

They have a trrminal for A B and ground. Ive seen ground recommended for long runs. Any thoughts? With a uart it looks like it handles the di do de re lines for you, which may be a blessing or a curse, certainly would need changes to mysensor code to use them.
