    Works as one would expect, since it appears to be a Waveshare product
  

*by V***D on Reviewed in the United States on 2 August 2023*

Converter works as expected, not sure what's up with the branding since it's got Waveshare logo on the unit and the box.Got a little isolating 5V DC/DC in there so it can provide power to the RS422/485 side without requiring a separate power supply.  Also jumpers for selectable termination resistors.  Nice separation between the hot and cold sides.  And TVS protection.  Pretty well engineered.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent design, genuine FTDI chip
  

*by A***4 on Reviewed in the United States on 11 July 2023*

It's clear that a lot of thought went into designing this serial interface converter. The USB and RS485/422 sides are thoroughly isolated from each other, to the extent that there's even an air gap built into the board. The RS485/422 circuitry incorporates extensive protection components, along with configurable termination resistors (selected via two onboard jumpers).The converter is housed in a sturdy plastic case that supports DIN-rail and surface mounting. The kit comes with a USB 2.0 A-to-B cable, plus a mini screwdriver for the terminal block. There weren't any instructions in the box, but the device is straightforward enough.In use, the converter performs well, with the genuine FTDI FT232RNL chip providing reliable and predictable operation. The RX/TX lights help with troubleshooting and are easy to see. Overall, excellent quality and functionality. Highly recommended.
