Review on 💻 Gearmo Pro 5ft. USB to RS-485/422 Serial Adapter - FTDI Chip, Windows 10 Support by Andrew Woodruff

I have used this little device to develop firmware for several building automation sensors based on PIC16 microcontrollers. The sensors are deployed on a multidrop bus that provides both RS485 based communication with the main controller and power supply. With a bit of cable, this device allowed me to communicate with all the sensors on the bus from a windows laptop using a small application I had written in C under Cygwin. RS485 is an electrical specification for a shared bus, and this little device handled my bus's electrical signals and protocol just fine. Now I'm at the point where I won't use USB to serial adapters that aren't based on an FTDI chip because their stuff just works and everything else is crap. Can't speak to using this in an RS422 environment, but it worked great for me!
