DSD TECH SH-U12 RS485 to TTL 5V Board With MAX13487 Chip for Raspberry Pi Arduino and other MCU

Q: Are there any instructions on how to use it? Send or receive Messages?

This is a "well behaved" product which seems to meet its specifications. I recommend this product for what it does. It works well for both send and receive. I have several of them. Serial communications can be a bit "tricky" so if you are not familiar with it, I recommend either a book or research on the internet. A full discussion of this subject is a bit beyond this forum. Good luck.

Q: Would it work with rs422?

Currently, only RS485 is supported.

Q: this item include the cables on the picture?

I don't know what picture you are looking at but - probably. The package included a 4 conductor cable approximately 12 inches long. It is designed to plug into the "TTL" end.

Q: Does the tx go into high-z (tri-state) when not transmitting, so it can be used on modbus or multi-drop lines?

Yes. It works well with Modbus multi-drop lines as long as your "master" is working according to spec. For the price, just try it to be sure it works for you.

these are the nuts

using them for all sorts of projects, i.e. communicating between 2x arduinos or 2x teensys. Great bit of kit.

this solved my RS485 connection problem

I tried several ways to get an RS485 anemometer to work with an ESP32 mcu. This adapter finally solved my problem. Once I had it hooked up, it worked.Plus very fast delivery.
