Overview
V6 pcb is an open-source printed circuit board by reven, from the reven/V6-conversion repository on GitHub. It is a 2-layer board of 431.5 × 126.8 mm with 374 parts on 263 nets, routed with 2,873 tracks and 554 vias.
It is built around the ATMEGA32U4-AU, USB6B1 and SK6812MINI-E. Its parts include 216 diodes, 109 switches, 6 capacitors, 6 resistors and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
README.mdKeychron V6 conversion
This project's goal is to convert a Keychron V6 Keybaord to north-facing LEDs.
It encompases:
- a pcb based on an ATMega32U4 that fits the V6 case and faceplate. These files are in the 'Hardware' folder.
- a qmk-based firmware for the ATMega32U4 powered 108 key V6. These files are in the 'Firmware' folder.
This was a fun project. I hope it can help someone that's doing something similar or just tinkering with mechanical keyboards.
Why
The south-facing LEDs weren't working for me. The light leaking under the keys blinded me when I typed with low ambient light, and the key-legends were hardly vissible. I couldn't find keycaps for south-facing LEDs that I really liked and I decided to try and design a new PCB as a fun side project.
Caution
-
If you decide to atempt something similar, you should know that the screw posts are going to be in your way. A couple of the hot-swap sockets are going to fall right next to a hole, and you are going to need to trim them in order to get them on the board. Mine has worked out well, but it required some finesse when soldering.
-
Using an ATMega32U4, while super easy to integrate and program for qmk, makes the keyboard matrix much more complicated than it has to (see below). You also lose the back switch.
PCBs
I have a few extra PCBs. If you are interested, let me know and I might be able to help.

Questions
How big is the V6 pcb PCB?
It measures 431.5 × 126.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V6 pcb use?
374 parts, built around the ATMEGA32U4-AU, USB6B1 and SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the V6 pcb KiCad files?
From the reven/V6-conversion repository on GitHub, at the commit this page was made from: the board is Hardware/V6_pcb/V6_pcb.kicad_pcb and its schematic Hardware/V6_pcb/V6_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the V6 pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask reven before reusing the design.
