516 B


fixes v0 short comings:

  • shield LED is on when both shell are interconnected and connected to ground (the cable could cheat by just connecting both shells directly to ground)
  • all GND and VBUS pins of USB-C are used


first prototype build.

it works, but almost only on specification compliant cables:

  • some cables don't have all 4 GND and VBUS pins in the C plug
  • normally the shield should connect both shells AND be tied to ground on BOTH ends, but I've seen ALL possible combinations thereof
