: Beyond standard Windows (XP through 11) and Linux support, it is highly compatible with single-board computers like the Raspberry Pi . When researching drivers

You won’t typically buy this chipset directly; instead, it is embedded in countless USB dongles from brands like TP-Link (TL-WN723N, TL-WN725N), Edimax (EW-7811Un), Linksys, D-Link, and generic "no-name" adapters. If you see a tiny, often blue or black, thumb-drive-sized Wi-Fi adapter from the last decade, chances are it runs the RTL8188CU or its close cousin, the RTL8188CUS.

The driver is included in the mainline kernel due to licensing issues (proprietary firmware). You have two options:

You will often see these two terms used interchangeably. Technically, the RTL8188CUS is a later revision with slightly better power management and integrated USB interface, but for the end-user, the drivers and functionality are identical. When researching drivers, looking for "RTL8188CUS" usually yields better results.
