The LCK75 is a through-hole kit keyboard with an encoder and OLED designed in mind mainly for beginners or the peeps that really like soldering.
This was originally my first design but after 2 successful rounds and changes, I've made within those rounds thanks to friends and feedback, it's back for a 3rd round.

pics of a white proto with gmk Modo r1, USB is THT here, but it shouldn't matter
and the backplate logo will not be silkscreen as it doesn't look good when the silkscreen
is that spread out so copper islands will be used instead just like the previous rounds of the LCK75
