Adafruit Great Scott Gadgets Cynthion - All-in-One USB Multitool

Great Scott Gadgets' Cynthion is an all-in-one tool for building, testing, monitoring, and experimenting with USB devices. Built around a unique FPGA-based architecture, Cynthion’s digital hardware can be fully customized to suit the application at hand, allowing it to serve as a high-speed USB protocol analyzer, a USB research multi-tool, or a USB development platform.

Out-of-the-box, Cynthion acts as a USB protocol analyzer capable of capturing and analyzing traffic between a host and any Low-, Full-, or High-Speed USB device. It integrates seamlessly with their open-source analysis software, Packetry, for detailed insights into USB communications.

When combined with LUNA gateware and Facedancer libraries, Cynthion transforms into a versatile tool for USB research and development. Facedancer simplifies the creation or modification of real USB devices, a feature particularly useful for those without experience in digital hardware design, HDL, or FPGA architecture.

Please note that no extra cables are included with the device; you may require various USB A & C cables to connect to your computer or target devices.
