The Simplecom NB540 USB Bluetooth 5.4 Adapter is a cutting-edge wireless dongle designed to seamlessly add Bluetooth connectivity to your PC or laptop. Leveraging the advanced Bluetooth v5.4 protocol, this compact adapter offers superior device discovery speeds, enhanced data transfer rates up to 3 Mbps via EDR, and significantly reduced power consumption thanks to Bluetooth Low Energy (BLE) support.

Optimized for Windows 7, 8, 10, and 11 (32/64-bit), the NB540 is plug-and-play compatible with Windows 10 and later without manual driver installation (internet connection required). Older Windows versions (7 and 8) require driver installation via CD or download. This dongle enables stable and efficient wireless connections to a broad range of devices such as keyboards, mice, headsets, speakers, printers, controllers, and mobile phones.

Featuring Class II power with a reliable transmission range of up to 20 meters, the NB540 supports multiple Bluetooth profiles including SPP, ANCS, HFP, HCRP, A2DP stereo playback, and AVRCP for versatile applications. Its small form factor (22 mm x 14 mm x 6 mm) makes it unobtrusive when plugged in, powered directly by USB 2.0 at 5V.
