Hello! I wanted to add an external USBC port to my Proton C and I noticed that it had ports for D+, D- and 5V (CHRG).

My best guess is to take both data buses and run them through a Data ESD protection chip then connect D- and D+ to their corresponding ports. To run power I assume I should take the VBUS pin, attach a 1 amp fuse, and connect it straight to the 5V pin.

A follow up question is that I am using the NUF2221W1T2G for my Data ESD chip and it requires 3.3V to be fed. Could I hook up VCC to it and be done or will I need a power protection chip like the TLV70233.

Any advice or suggestions would be very much appreciated!

Hi QMK maintainers,

Is Proton-C PCB opensourced? Just plan to upgrade my atmega32u4 based keyboard to an Arm based MCU, found Proton-C may be a good example since I'm going to use QMK for the incoming Arm based keyboard.

I learnt about Proton-c here https://qmk.fm/proton-c/, and read it through, did a little bit of search and failed to find anything related to Proton-C's Schematic or PCB. If Proton-C is indeed opensourced, please add a ref to the https://qmk.fm/proton-c.

As you can see when using the qmk proton c schematic and footprint in KiCad some pins are extra in the PCB...
