Review: Easy to install, works great for extending WS2811 led strips - I had a WS2811 12V led strip that was connected to the controller about 30 ft away using sprinkler wire to transmit data. The length was too long and the signals were getting corrupted, so these modules came really handy. One was wired into the control box as the transmitter, the other into the box containing the led strip and set up as a receiver. Look for Arduino Nano TTL to RS485 and wire accordingly. No issues with signal degradation after installing a pair of these.
Review: Work reliably. Wish they were more compact. - These work fine. I wish they were a bit more compact. As is they’re impossible to use on a breadboard for prototyping due to length. But they do work and are reliable. And the included terminal block connectors make connection easy.

## Questions & Answers

**Q: What does the serial uart labels of di, de,re,and rd represent with regards to ground, rxd, txd, and vcc? thanks for help.**
A: ro: receiver output, re: receiver enable, de: driver enable, di: driver input, all TTL logic level signals. vvc is 5V, gnd is ground, A & B are the differential serial lines

**Q: Does this board provide isolation for the MCU?**
A: No

**Q: Which resistor do I clip out to eliminate the terminating resistor?**
A: That will be the one marked R7 (120 ohms) which needs to be removed for all drivers except the two on each end of the cable run. There are many images showing this if you Google for "Max485 Chip RS-485 Module".

**Q: Do you have a schematic for connecting these to a raspberry pi?**
A: If you Google "Max485 Chip RS-485 Module" you'll find many examples of how to connect  to Pi and many other controllers.

### ⭐⭐⭐⭐⭐ Great item
*by A***R on October 25, 2018*

Did exactly what I needed it to, connect two Arduino boards over long serial lines to do half duplex communication. Tie the DE/RE pins together, and attach to a digitial out on the arduino. Tie the TX/RX to the arduino uart. Drive a high/low after a delay allowing bootloader to function as normal, and provide the ability to select TX/RX from within your program. Layout of VCC/GND pins could be a bit more convenient if they were not on the same header as the A/B bus.
