USB 3 port support? #1

Hi (hope this is the best place for this question!),

First of all amazing work, thanks for doing this. This is really the only place on the web I could find of even the possibility of extracting higher amps from USB c via PD...

I am working on a USB C connection cable for my Lacie Rugged Raid, which can only be bus powered from TB2...

The only thing needed in addition to your work would be a USB3 instead of USB2 port. How much work do you think this would be?

Also have you thought about integrating an ATMega into this board for voltage negotiation, so that the user could select voltage and amperage via jumper pads?

Thanks again!!

Hi elggem,

I just noticed this message. (I'm not the best at using github). You've probably already moved on, but I figured I'd answer just in case.

As for adding a USB3 port, it adds a lot more complexity. More specifically, the USB SuperSpeed lines run at much higher speeds, so routing is tricky and board cost goes up significantly. I have a few ideas for projects that will use it, and I'll see if I can add it to a more specialized breakout board.

As for adding a microcontroller to my breakout board, I've done exactly that. I've released the USB-C Explorer, which uses a SAMD21, similar to the Arduino M0. Right now it will go for up to 20 V if it can, but the firmware can easily be modified. You can check out the design here and buy one here.

Sincerely, Jason
