StarTech.com 24in Internal USB Motherboard Header to 2 Port Serial RS232 Adapter

Product Overview

AI-generated summary

If you’ve got a desktop/workstation motherboard with an internal USB header and you need real RS-232 serial ports without getting involved in PCIe cards or hunting down legacy hardware, this StarTech adapter is exactly the kind of “just make it work” solution you want. At £49.40 ex-VAT it’s priced like a proper business tool rather than a gamble, and StarTech’s serial adapters tend to be fairly reliable in the real world (the big differentiator vs no-name USB-to-serial leads is usually driver quality and consistency across systems). It’s a good fit for things like POS/label systems, some industrial peripherals, or any admin-led maintenance where you want to keep the machine’s expansion slots free.

That said, I wouldn’t buy it if your environment is mainly modern RS-232-over-network appliances or you’re expecting plug-and-play with older software that’s picky about COM port settings. USB-to-serial solutions can still introduce driver friction, and you may need to verify COM port assignments in your application. Also, if you already have serial on a motherboard/PCIe, paying nearly £50 for two ports is hard to justify. But for IT teams standardising on “internal USB header → two dependable serial ports”, this is sensible value and likely less hassle than alternative approaches.
