The UGREEN CM748 (45134) adds Bluetooth 5.4 wireless to desktops and laptops through a compact USB-A connection.
Bluetooth 5.4 connectivity
Uses Bluetooth 5.4 with EDR and BLE support, and remains backward compatible with Bluetooth 5.3, 5.2, 5.1, and 5.0.
Multi-device pairing
Pair up to five devices at once—mice, keyboards, phones, and other peripherals. When two audio devices are connected, only one can play music at a time.
Range and performance
Bluetooth 5.4 extends wireless range for everyday use; obstacles can reduce effective distance. Data transfer is designed for low latency with strong anti-interference behavior.
Windows compatibility
- Windows 11, 10, and 8.1: plug-and-play; no driver required
- Windows 7: drivers required
- Linux: not supported
Design
Compact USB-A form factor sits flush enough to avoid blocking adjacent ports on many systems.
