Technical Specifications

Compatibility & Important Information

The MU002 supports both the supplied 2.4 GHz wireless connection method and Bluetooth 5.0 / 3.0. UGREEN specifies compatibility with Windows, macOS, Android, iOS, Linux and Chrome OS systems within the versions listed above.

This exact 90321 configuration uses one AA battery. It should not be described as a rechargeable 500 mAh lithium-battery mouse, as that specification does not match UGREEN's official MU002-90321 product data.
