- For
- USB-PD engineers, hardware experimenters, and protocol researchers
- Worth noticing
- The lab focuses on 240W USB PD 3.1 EPR behavior, including AVS, SOP/SOP' traffic, and CY4500 analyzer tooling.
Field notes
The project centers on the less visible mechanics of USB-C power: EPR negotiation, AVS, PDO behavior, packet capture, and analyzer workflows. Its available cy4500-cli project targets Infineon CY4500 and CY4500-EPR hardware, while the homepage says measurement data, hardware notes, and further documentation will be added progressively. External links point to repositories, updates, videos, and a Roblox game.
