OEM Bluetooth 4.0 USB modules (v2.1 back-compatible)

This adapter is backward compatible with v2.1 and earlier, but also supports the latest version 4.0/Bluetooth Low Energy. Inside, it features a CSR8510 Bluetooth USB host. Drivers for CSR Bluetooth modules are integrated into Windows XP/7/8/10. You do not need to install any software or download anything: other Bluetooth drivers or stacks like BlueSoleil are not as good as the Windows stack and may cause issues. Simply plug it in and get started. Windows will automatically install the BT driver, which may take a few minutes.
