done the slave half and backlight for keys

so yeah, i made the other half, worked the wiring again, and uh, added backlight for each key, absolute pain, not a good idea, and uh, I FORGOT THE NET THING, and uh, everything dont have a net, so DRC IS COMPLAINING, but ill let him cry until i find the mood to do it

reworked the master half pcb

so yeah, i decided to rework it, as i find out i made some mistakes lol, like i connected the GND to the RX wire accidentally, and i just found that i can make the pcb even better, so i organised it and also added some heidi pics :3, thats how the pcb looks like (with raytracing on a i5 gen 3 )

finished the master side of the pcb

so yeah, i made the pcb, it was pretty hard, and for the usb-c, i had to connect it to a fan pin, then i will modify a micro usb cable so i can connect this to the usb-c, i will prob use pin sockets for the pico, bc i want things to be modular, and yeah, i think thats it

remade the schema

so yeah, i wasnt really happy with the micro controller i used before, and it will also be hard to find one here, so i decided to use the classic rpi pico, i also used the TRRS to connect the other half, im still not sure abt this part tho, this will ofc use the QMK frimware, also thats the schema for the left (master half) keyboard
