The UGREEN CM401 connects a compatible computer to an SD or microSD memory card through USB 3.0.
Simply connect the reader to an available USB-A port, insert your card into the corresponding slot and access the files through your device’s file manager. The reader supports plug-and-play operation on compatible systems, so a separate driver is generally not required.
Key Features
