Works Well
This USB adapter has 6-in-1 functionality allowing you to convert USB to RS485, RS232, TTL to RS232, RS485, and more. This makes it a very handy device.I've been using it for my Arduino projects, and it has made connecting different devices very easy. The data transmission is seamless, and it works great with various devices.It even comes with a 6P female-to-female cable, making it even more versatile. If you're into electronics and need reliable and flexible connectivity options, this module is a great choice. I would recommend.

Takes a bit of getting to work, but good results.
It took me a while to get this to work as I wanted (talking to Arduino to provide a 32 bit I/O interface for my computer) but all was good once I could send/receive data.Simple circuit with no instructions but does come with small jump leads to a prototype board and is comparatively cheap.
