Bluetooth 5.3 USB Adapter for Windows

The AUTYUE A03#Q2178_B adds Bluetooth 5.3 to desktop PCs through a USB 2.0 port. It supports Windows 11, 10 and 8.1 for keyboards, mice, headsets, printers and speakers. The adapter uses the ATS2851 chip and operates on the 2.403 to 2.480 GHz band. Its ultra-compact frame measures 15 x 15 mm.

Sustained throughput at 3 Mbps

The adapter maintains a maximum transmission rate of 3 Mbps during continuous transfers. Bluetooth 5.3 keeps latency low and the signal stable across walls at 10 to 20 metres unobstructed. You can connect up to 5 peripherals simultaneously without noticeable dropouts. Plug-and-play operation requires no extra drivers on supported Windows versions.

10 to 20 metre range decides desktop placement

The practical unobstructed distance of 10 to 20 metres determines whether the dongle reaches your devices across a room. If your PC sits farther from the keyboard, mouse or speaker than this range allows, the link will become unreliable. Buyers needing longer reach should consider a USB extension cable or a different class of adapter.
