Question asked some time ago about soldering a new USB 3 connection. I do not need a new one, just a moved one. One reply contained the following.
The connection is for a USB 3 disk so I need the USB 3 speed. There are USB 3 flat cables. I am looking at one to run under the Pi 4 to provide a USB 3 port at the other end of the Pi 4 board.
When I look at the underside of the Pi 4, the USB 3 port has four big mounting blobs and two sets of two rows for the ports. Each set is one row of four solder points and one row of five points. The USB 3 spec contains the following. Does that mean I can cut into a USB 3 cable and solder one on if i get the nine wires correct?you can move an existing USB port to a new USB connector simply by extending the connections from an existing USB by soldering the four wires (+5V, B+, B- and GND) to the underside of the PI.
