If any one wants to create a mechanical keyboard and use the controller board of the logitech k120 , there are some extra keys on the keymap that are not present on the actual keyboard but was present in the matrix , like the shortcut keys and the volume up and down keys , as well as the power and sleep keys.
Have other mass produced co troller boards been mapped like this?
Dont know to be honest i guess others can be mapprd out too , however i chose this keyboard cuz k120 keyboard design is like 20 years old and plenty available in all over the world so it will be easily replicable .
This seems like an interesting approach to building budget boards, and reducing ewaste at the same time.
Hey i was mapping out my broken keyboard :) to try and making a mechanical keyboard. But the pin out makes it hard to design a pcb
update print screen is pin 13-3
Nice! This is a neat service, I think. If you can add it to Deskthority.net, that might be a good archive place? I've never tried adding anything there, but I'm also pinning out the controller board of the Cherry Multiboard v2 for a project, and was planning on learning how to contribute for that.
Edit: Could you share a photo of the other side of the controller board?
Hey thanks I will try to add it to Deskthority.net , and keep up with the cherry multiboard V2 project .
I will share the other side of the controller board .
Thanks! I was hoping to see a QMK compatible chip (perhaps naively), but no chip at all is a surprise!
the controller is under the blob
Ah, of course. That blob doesn't come off easily by any chance, does it?
nop it will destroy the controller i am pretty sure
I am not reciving a confirmation mail on Deskthority :( any other forum that i can share on ?
It's the only wiki-like page I know, but else you can post it on Geekhack.
This is really cool, thanks! Can you solder to the pins on those controller boards? They look black
Yea the black thing is just graphite on top of copper pad , on the first pin i have scraped it off and the copper is visible so just need to scrape the graphite off and good to solder :)
