Review on 🔌 DTECH USB to RS422 RS485 Serial Port Converter Adapter Cable - Support for Windows 10 8 7 XP Mac - High-Quality 1.5 Feet Cable with FTDI Chip by Gregory Flynt

Very nice product. It supports full-duplex and half-duplex communication and a ground connection. The packaging is really nice, with a sturdy box, inner sleeve and even a mini disc with drivers on board. The device uses an FTDI chip (I haven't looked at the board but it uses FTDI drivers) which is generally good quality. Automatically negotiates the communication method so it only works when there is a connection. Definitely recommended. It's nice when your debugging hardware doesn't have to debug itself.
