Bluetooth 5.3 USB Adapter for Windows 10 and 8.1

This SMA A4#Q2119_B dongle adds Bluetooth 5.3 to a desktop or laptop running Windows 10 or 8.1. It is driver-free on those systems, so installation is plug-and-play. The adapter is not compatible with Windows 11 22H2, Windows 7, macOS or Linux.

Bluetooth 5.3 with 100-metre open-space range

The single specification that decides fit is the Bluetooth 5.3 radio rated for up to 100 metres or 328 feet in open space. Backward compatibility covers versions 5.2, 5.0, 4.2, 4.0, 3.0, 2.1, 2.0 and 1.1. Physical obstructions and wireless interference will reduce the practical range.

Low-energy radio with multi-device support

Bluetooth low energy keeps power draw minimal during normal use. The adapter can maintain simultaneous connections to five Bluetooth peripherals such as keyboards, mice, printers, headphones or speakers. Audio streaming supports aptX, AAC and SBC codecs, though only one audio device can be active at a time.
