They just work
This was the second try for this type of equipment. First one (3.3V, auto direction) did nor work. These worked like a champ.

Works, but may have to remove R7?
After multiple failed attempts to get 2 of these boards communicating with each other, I found something that mentioned a "terminating resistor" (R7) that should only be present on the last device in your RS485 run. I removed R7 on two boards and they successfully exchanged messages with each other. I have not yet tested more than 2 devices communicating on the same bus. I'm not sure yet if it will work if none of them have R7 installed. Also, if you are attempting to use these with arduino and the software serial library, this might be a helpful hint: pay attention to which pins have interrupt capability. You must receive serial data using an interrupt enabled input pin. The boards themselves seem reasonably well made. Solder joints all look good.

Nope
These things are junk, 8 of 10 got really hot and the LED burned out none of them actually connected to each other I don't think

Led differential signal
Used these and an ethernet cord to get led differential signal over 50 feet when the single ended data line wasn't powerful enough.

Most do not work, there is no TTL output.
Most do not work, there is no TTL output for those that do not work. Also came with two different style boards which I thought was a bit sus.

Can Be difficult to figure out proper wiring for use with WLED
Took some digging to figue out how to use as with WLED for long cable runs. The main thing is: on the transmit side connect DI to your development board. connect RE and DE to VCC on the transmitter on the receiver side : connect Ro to what ever you are sending data to ( in my case, the LED data line connect RE and DE to GROUND.

Unreliable, high failure rate.
More than half of the units failed within the first few power cycles. Purchase the XY-017 instead.

Flakey, easily destroyed
It's a good thing that these come in a multi-pack. One was DOA and two failed after a very short time.
