Bluetooth 5.1 USB adapter for Windows PCs

This SMA Z2#Q2324_B dongle adds Bluetooth 5.1 + EDR capability to desktops and laptops that lack built-in wireless. It supports dual-mode operation and connects mice, keyboards, headsets, speakers and printers simultaneously. The adapter is designed for Windows 11, 10, 8.1 and 8 with plug-and-play installation. Mac OS, Linux, TVs, car stereos and game consoles are not supported.

Class I radio with external 2.4 GHz antenna

The adapter meets the Class I power standard and uses a 2dBi external antenna to reach up to 328ft or 100M in open space. Bluetooth 5.1 + EDR delivers a 3Mbps data rate while reducing power consumption compared with older versions. Physical obstructions and wireless interference will reduce the practical range. No driver is required for Windows 11, 10, 8.1 or 8.

Driver required for Windows 7 only

On Windows 7 the bundled driver must be installed from the supplier support site before use. The manufacturer advises disabling any built-in Bluetooth radio before inserting the dongle to avoid conflicts. Windows 11, 10, 8.1 and 8 recognise the device automatically without extra software. The package includes the adapter and access to the downloadable driver.

Questions about this item

How do I install the SMA Z2#Q2324_B Bluetooth 5.1 adapter on Windows 7?

Disable any built-in Bluetooth driver first, then plug the adapter into a USB 2.0 or 1.1 port and install the driver from the supplier's support site (sz e d up(dot)com/support/driverdownload/bluetooth/b3536/). Windows 11, 10, 8.1 and 8 are plug-and-play and need no driver.

What maintenance will the external 2 dBi antenna need over time?

The antenna is a passive component with no moving parts or firmware; no scheduled maintenance is required. Keep the connector clean and ensure the antenna remains securely screwed into the adapter for best 2.402–2.48 GHz signal performance.

What limits the 328 ft range first during sustained use?

The 328 ft / 100 m figure applies to Class I power in open space; physical obstructions and wireless interference on the 2.4 GHz ISM band typically reduce the practical range well before the adapter's 3 Mbps EDR throughput or Bluetooth 5.1 low-energy features become a bottleneck.
