The EDUP EP-B3531 adds Bluetooth 5.3 to a PC through a standard USB port. It supports Windows 11, 10 and 8.1 without requiring a separate driver installation. The adapter works with mice, keyboards, headsets, speakers and printers. It is not intended for car stereo systems, game consoles or televisions.

Range and speed limits of Bluetooth 5.3

Bluetooth 5.3 operates in the 2.4 GHz to 2.4835 GHz band and delivers a maximum transfer rate of 3 Mbps. The quoted open-air reach is 22 metres or 66 feet. Performance will drop through walls or in crowded radio environments. The adapter remains backward compatible with Bluetooth 2.0, 2.1, 3.0, 4.0 and 4.2 devices.

Nano form factor leaves adjacent ports free

The black dongle measures 0.93 by 0.59 by 0.24 inches, so it sits almost flush with the chassis and does not block neighbouring USB sockets. Its low profile lets you leave it plugged into a laptop during transport. No external antenna or separate power supply is required.
