## Description

desertcart.com: USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection : Electronics

Review: Works great - 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.
Review: Works awesome for managing my ESS system. - 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.

A: This is a RS485 serial port adapter, the serial port is always on.  If you have a RS485 relay module, the module will alway be on to, that module will control a relay, that it turns on and off by command over the RS485 serial connection.

**Q: Will this work with the usb 2.0 on an rpi 3b? currently, when i hook plug it in, the os finds the adapter but then crashes the rs485 bus.**
A: Hi,it can work with the usb 2.0 on an rpi 3b.
If it is crushed ,it can be caused by low electricity

Perfect, not too expensive and the extra usb extension is really nice to come with the adapter. The rx & tx lights are useful to see. Simple to install the wires. I tinned the wires just for fun.
