ASUS USB-BT540 Bluetooth 5.4 USB 2.0 Type-A Bluetooth Adapter

ASUS USB-BT540 is a compact Bluetooth adapter that gives you an easy way to add wireless connectivity to a desktop computer or laptop via a standard USB port. It is positioned as a practical and affordable solution for everyday devices – mice, keyboards, headphones, speakers, and other accessories. It operates at a frequency of 2.4 GHz and uses Bluetooth standard for stable short-range communication. The transfer speed of up to 3 Mbps is more than sufficient for audio, peripherals, and basic file sharing.

What you get

You connect the adapter via USB 2.0 and immediately have Bluetooth capabilities on a machine that normally does not have such a module. With data transfer of up to 3 Mbps, you can comfortably stream music to wireless headphones or speakers without noticeable delays. Operating at 2.4 GHz frequency allows good compatibility with a wide range of Bluetooth devices, as long as you do not have too much interference from other 2.4 GHz sources. The built-in support for Security Manager Protocol helps for more secure pairing and encrypted connection between the adapter and your devices. The lack of an external antenna means a more compact form factor that does not protrude and does not interfere, especially if you use front USB ports or closely spaced connectors.

Who it is suitable for

This adapter is a good choice if you want to quickly and cheaply add Bluetooth to a desktop computer or older laptop for connecting peripherals and audio devices. It is suitable for office work, home use, light gaming accessories, and wireless audio. It is not optimal if you are looking for a large range through several walls or have a heavily „polluted“ 2.4 GHz environment with many other wireless devices.

The combination of a simple USB 2.0 interface, 3 Mbps Bluetooth transfer, and Security Manager Protocol makes ASUS USB-BT540 a practical little addition to almost any PC when you need stable basic Bluetooth connectivity without unnecessary complications.
