Using headers for board to board connection
Warning: the connector is symmetrical and thus does not have a polarizator: do not connect the
modules the other way around, or you will damage them forever. To help you, the connecting
contacts of the USB modules have all a square pad at one end, corresponding to the ground of the
USB bus. The square pads must coincide when connecting.
Beware of the direction of the connection!
3.2. Direct soldering of ribbon cable
You can decide to connect your peripherals with 1.27mm ribbon cable. Choose solid copper cable,
this cable is less supple than a threaded one, but much easier to solder. Get the direction right:
square pads must coincide.
You can solder ribbon cables.
3.3. Direct soldering on the up port
If you believe that the Micro-USB-Hub-V2 takes too much room in your project, you can eliminate the
up port connector, and solder a USB cable instead: cut the printed circuit with the help of a good
pincer and, if needed, sandpaper the protruding parts. You only need then to solder the cable on the
contacts designed for this. Caution: Get the direction right: orientation of the pad on the up port is the
other way around compared to the neighboring down ports. You can solder the shield of the USB
cable on the pad designed for it, right next to the contacts for the wire.
