Mini USB Bluetooth 4.0 Dongle

The StarTech.com USBBT1EDR4 is a Class 1 Bluetooth 4.0 adapter that plugs into a USB 2.0 port to add wireless connectivity to a laptop or desktop computer. It supports Enhanced Data Rate with transfer speeds up to 3 Mbps and operates at distances up to 50 metres (165 feet).

Suited for older Windows and macOS systems

This adapter works natively with Windows XP through Windows 11 and Windows Server 2003 to 2022, plus macOS 9.x, 10.6 through 10.15 and 11.0 to 15.0. It is not suitable for computers that lack a USB Type-A port or for users who require a Bluetooth version newer than 4.0.

Class 1 range up to 50 metres

The single specification that determines fit is the Class 1 radio, which provides an effective operating range of 50 metres (164 feet) — far beyond typical Class 2 dongles. If your devices must stay within a few metres, a shorter-range adapter would suffice.

Questions about this item

How do I choose between this USB Bluetooth 4.0 adapter and other versions?

This model is a single USB 2.0 Class 1 dongle with 50m (165ft) range and EDR up to 3 Mbps; there are no alternate capacities or versions listed for this MPN.

What does the 3 Mbps EDR rate mean once the adapter is plugged in?

The Enhanced Data Rate ceiling of 3 Mbps is the maximum over-the-air throughput; real-world speeds will be lower due to protocol overhead, distance, interference and the capabilities of the paired device.

What does the USB 2.0 interface cap in practice?

The adapter uses a USB 2.0 port for power and data; the 3 Mbps Bluetooth EDR limit is well below the USB 2.0 bulk-endpoint bandwidth, so the USB bus does not throttle the wireless link.
