Cynthion: hardware design for a USB test instrument

Cynthion is an open source hardware tool for building, testing, monitoring, and experimenting with USB devices. It is the primary platform for the LUNA USB gateware library based on Amaranth HDL.

Schematic PDF and fabrication outputs may be found in release archives. See the Cynthion Documentation for additional information.

Cynthion is designed in KiCad, an open source electronic design automation package.
