Adding USB by Fabricating a MAX3421E #FeatherWing

Hackaday.io user davedarko is designing a FeatherWing add-on board for Adafruit Feather sized microcontroller boards. The board will provide USB connectivity over a SPI bus using the MAX3421E chip. The MAX3421E is a USB controller that can function either as a USB peripheral or host.

I did something I haven’t done before on this board, a matrix to reroute pins with solder jumpers. Otherwise the board looks fairly simple and boring, not much to route on it.
