Hello.

I already desoldered the SDL socket of my Model M. Now is the question: Which lines go to which?

My micro USB socket has GND, 5V, D+, D-, ID

(ID is not needed afaik)

Has someone an idea?
There are 6 lines available, lets call them
D E F
A B C

(viewed from the front, where the plug was former)

Hi,

this picture helped me a lot back when I soldered my pro micro board: workshop-f7/xt-at-ps2-terminal-to-usb-c ... ml#p298197

I have probably recommended taking photos of "original configuration" before dismantling it more times than I have actually followed my own advice. Somehow the lust for tearing into something over-rides the good common sense of making sure than you can get back to your starting point.

I guess my pinout is fine, tough it doesn't work.
I ONLY use an socket, so no controller.

Could it be that I HAVE to use either an ps2/usb converter or an pro micro/teensy?
