USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection

Works flawlessly and super inexpensive. What more can you ask for.

I bought this to connect my PowMr all in one solar inverter to Solar Assistant on an Orange Pi. I was using the USB port on my inverter but it suddenly stopped working one day. At first I thought maybe my USB cable was bad so I tried a couple others but no luck. The price is very reasonable and not much more than a USB cable. Very easy to hook up. My inverter uses an Ethernet port for RS485 - I just cut the end off of an old Ethernet cable and hooked up 2 wires to the Waveshare and plugged everything in. Build quality appears to be good. It's been working fine for about a month now.

I paired this WaveShare RS-485/FT232RL USB interface converter with a thermister temperature collection module to monitor my beer fermentation process. The converter installed easily on my Windows XP SP3 Intel Pentium 4 HT laptop. Many thanks to FTDI for not deprecating Win XP from their driver set! The status LEDs were great confirmation that my software was communicating with the temperature board, or at least trying to during initial development. Once my code was completed, the WaveShare converter demonstrated good stability in 24/7 use during the last two weeks of my fermentation (the brew was started before the software was complete). I was nervous about trying to integrate these components on such an old laptop, but it all worked as desired. I hope this system description is helpful to lend confidence to others who are interested in a similar experiment.

This says no driver required, but my computer (LG Gram running Windows 11) immediately flagged it as unknown and said it was missing a driver. I found the driver on the ftdichip website and now it works. I'm using it to connect to a Samsung HVAC system. The official Samsung version of this costs 1k. Down with big HVAC!

Excelente producto

This is my second time purchasing these. They work great for use with all my PV, inverter and battery (ESS) equipment. I’ll need about 16 more units. Waveshare manufactures them right.

Es de una buena calidad y hasta el momento no he tenido problemas de perdidas de datos o falla de comunicación por culpa del convertidor usb.

Product works great, have bought many times but shipping was delayed 2 whole weeks. I needed them the initial week I ordered them... Otherwise good product.

I use it to connect on BACnet MS/TP devices and networks to change settings on job sites and it's very easy to use. Just make sure of your polarity! If reversed, nothing shows up. I use it with YABE, a free software and it's just perfect, I can see all the BACnet points and change everything I need without issues.
