Title: YMDK Case USB C Daughterboard
Post by: holycow234234 on Mon, 31 May 2021, 23:04:22

I made a usb c daughterboard for the YMDK/Aliexpress tkl case.

I made this for myself, but I hope someone else finds it useful.
(Be gentle this is my first design)

It installs the same as the regular daughterboard, you just have to push fairly hard so the screws cut threads in the plated holes.

BOM:

GCT USB4105 Usb type C port

2x 0805 5.1k ohm resistors

Thanks. I was very curious about this case. Which main board did you used?

Thanks! I'm probably going to use it. I bought 2 of these cases with the hope of making a cheap alu TKL. Also very interested to know what PCB you used!

I used the xmmx board https://geekhack.org/index.php?topic=93422.0 (https://geekhack.org/index.php?topic=93422.0) (read my replies towards the bottom)
Couple issues I had:
My included cable wasn't long enough so I would have had to extend it, but,
I didn't have enough clearance to connect the jst connector so I ended up just hardwiring it, you might have better luck with a right angle connector.
