So I found the USB to stereo plug adapter in the store, But I did not see the connector that connects the board to this. The manual for the board says where to order parts to make one, But I was hoping to find one pre-made. (edge adapter)

Did I just overlook it in the store or is there not one? And to be clear I know they sell the stereo plug you can solder on, what i am looking for is a slid on clip to the end of the board (edge adapter) with the stereo plug to connect with so its not a permanent connection.
