I have been investigating a new design to offer a single cable experience for Raspberry Pi 4 & 5 with a full function USB-C connector that carries power, video, audio, USB 2.0 data.

In this video, I am showing testing of a reference design and overall plan to implement this.

The IC that does the conversion is from Lontium Semiconductor (LT6711A).

If you like this idea and would like to see it come to life, please let me know if the comments and let me know if you have any thoughts on improving the design or other features you'd like to see.
