Custom 65% Keyboard designed in KiCad, using an ATmega32U4 and QMK (C) firmware

When I was 15, I bought my first custom mechanical keyboard: a QK60 from Qwertykeys alongside Gateron yellow switches and some cheap keycaps from amazon. However, I encountered a problem when I accidently took out the PCB with the JST connector still plugged in, ripping the socket on the daughterboard (where the usb-c was). Devastated, this experience essentially brought me into PCB design through online guides and communities. 2 years later, with more PCB design experience, I decided to create my own 65% keyboard (my personal favorite form factor. Who uses the numpad anyways!?).
