Give Your Windows PC Bluetooth 5.3 - or Add Five More Connections to What It Already Has

The Astrum BT050 is a compact USB-A Bluetooth 5.3 adapter for Windows 11, 10 and 8.1 computers. Plug it in and Windows installs the driver automatically - no CD, download or app to configure.

Connect Up to 5 Devices at Once

Pair up to five Bluetooth devices simultaneously, such as a mouse, keyboard, game controller, printer and headset. Input and accessory devices can work together, while one Bluetooth audio device - such as headphones or a speaker - can play sound at a time. Switch between audio devices through Windows Sound Settings whenever needed.

Plug-and-Play Setup

No manual driver installation is required on Windows 11, 10 or 8.1. If your computer already has built-in Bluetooth, disable it first in Device Manager to avoid a driver conflict. The included user guide provides the setup instructions.

Compact, Stays Out of the Way

At just 33 × 16 × 8mm and 3.2g, the BT050 is compact enough to leave plugged in without blocking neighbouring USB ports. An LED indicator shows pairing and connection status at a glance.

Reliable Range

Bluetooth 5.3 provides a wireless range of up to 15 metres in open, obstacle-free conditions, giving you freedom to use connected devices around your desk or room.
