!!!!DO NOT use this coupler to connect two host devices (i.e computers) or you risk damaging them!!!!

I made this USB coupler so I could plug USB devices into the DE-10 with normal USB cables.

Solder two USB breakout boards together as close as possible with a 4-pin header in 2.54mm pitch. Make sure the PCBs are parallel to each other. Trim protruding pins or they don't fit in the shell. Please refer to the photo.

Use two M3x12mm screws and hex nuts to secure the shell.
