Title: My USB Type-C mod for KC60
Post by: Dan on Wed, 09 August 2017, 05:37:34

Just wanted to share my USB Type-C mod for a KC60. http://imgur.com/a/RtM45

The problem: dropped my KC60 keyboard off the side of my bed too many times and the connector got all mangled up.

Here is the housing disconnected from the board with the pins exposed.

Desoldered the pins from the board.

[attach=3]
Soldering wires onto the USB Type-C breakout board.

[attach=4]
Soldered the breakout board onto the main PCB board and put a little electric tape to insulate the housing. I used the post-its to keep track of which pins solder where, and testing results.

Hot glue and clamp.

The connector didn't lie flush so I had to file the hole a little larger.

Care to share the results of your testing? Planning to do the same for my keyboard.

Oh of course, it works perfectly. I'm using it now at work.
Tried it on Fedora 25 and Windows 10.

Oooh. Cool! Where did you buy the usb-c breakout board? Also, which pins on the keeb connect to which pins on the breakout board?

I bought the breakout at fasttech here: https://www.fasttech.com/product/2412400-u3-206-smt-type-usb-3-1-type-c-female-socket
It was over a year ago since I bought them so you may be able to find them cheaper elsewhere.

For the pinout mapping, I only needed to check wikipedia (make sure to look at the receptacle images, not the plug end):
* USB-C pinout: https://en.wikipedia.org/wiki/USB-C#Connector_pinouts
* USB Mini B: https://en.wikipedia.org/wiki/USB#Host_and_device_interface_receptacles

From there, I drew up a little diagram of what should connect where. Notice how they're replicas of the images I found on wikipedia.

The USB C breakout boards I bought didn't connect side A to side B, so I had to make some extra connections from one side to another (the loops you see in the images).
For example, as noted in the post-it image, A6 and B6 both had to be connected together, and also connect to pin 3 of the USB Mini B spot on the PCB board. On the post-it I used 'C' to denote the Mini USB B pins.

Hope this helps!
