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.
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
