Usb pmod
About the Usb pmod PCB
Usb pmod is an open source PCB design by tomverbeure, published on GitHub. It is a 4-layer board measuring 38.1 × 18.3 mm, with 14 components from 12 distinct parts.
Other key parts include the STUSB03E. By type, the board carries 5 connectors, 5 resistors, 3 capacitors and 1 IC.
From the project
It's common to implement Full Speed or Low Speed (FS/LS) USB host or device controllers on an FPGA by just using their digital IOs, configured as 3V3 LVCMOS.

A good example is the TinyFPGA BX board, which comes by default with a hardware-only USB device controller that's used to program new bitstreams into flash.
Another one is Fomu, another FPGA development board that's about as tiny as the USB Type-A connector itself.
