- The Simplecom NB540 is a compact USB Bluetooth 5.4 adapter that adds wireless connectivity to Windows-based PCs and laptops. It supports the latest Bluetooth 5.4 standard whilst maintaining full backward compatibility with earlier Bluetooth versions, ensuring broad device compatibility. The adapter features Bluetooth Low Energy (BLE) technology to minimise power consumption, making it ideal for environments where energy efficiency matters.
With a Class II transmission range of up to 20 metres and support for multiple Bluetooth profiles including A2DP stereo playback, the NB540 handles diverse connectivity needs from audio streaming to peripheral connections. The compact form factor makes it unobtrusive on desktop setups, whilst the USB 2.0 interface draws power directly from your computer with no external power supply required.
