Ummm... wut?

Can someone explain to me what this is used for?

It's a PCIe RS232 9-pin serial port card at a stupid price.

Not very useful except for edge cases.

I'm finding so many weird components on Wish. Its kinda fun to guess wtf they are used for.

Today, RS-232 has mostly been replaced in personal computers by USB for local communications. Advantages compared to RS-232 are that USB is faster, uses lower voltages, and has connectors that are simpler to connect and use. Disadvantages of USB compared to RS-232 are that USB is far less immune to electromagnetic interference (EMI)[dubious – discuss] and that maximum cable length is much shorter (15 meters for RS-232 v.s. 3 - 5 meters for USB depending on USB speed used).[9][10]

 

In fields such as laboratory automation or surveying, RS-232 devices may continue to be used. Some types of programmable logic controllers, variable-frequency drives, servo drives, and computerized numerical control equipment are programmable via RS-232. Computer manufacturers have responded to this demand by re-introducing the DE-9M connector on their computers or by making adapters available.

 

RS-232 ports are also commonly used to communicate to headless systems such as servers, where no monitor or keyboard is installed, during boot when operating system is not running yet and therefore no network connection is possible. A computer with an RS-232 serial port can communicate with the serial port of an embedded system (such as a router) as an alternative to monitoring over Ethernet.

TL;DR: it's like USB, before USB existed. certain devices that use the RS232 connector aren't obsolete yet though, so solutions like this card still exist for those users of those devices.

 

that doesn't really excuse the price though.
