README
README.mdHHKB universal-vault
The HHKB universal vault aka "omnivault" aka "v-all-t" is a community, open source pcb for the HHKB vault35. It tries to cover as many alpha layouts as possible while maintaining the original bottom row of the vault35. It uses a STM32F072 to reduce the amount of components while still supporting RGB for underglow.
Layout
The following Alpha Layouts are included and labelled with letters:
- V = Original Vault Layout
- A = Alpha Stagger
- O = Ortho
- K = Katana
- U = Uniform Stagger
- T = Treadstone
1 Oled is supported in two positions. 2 Rotaries are supported in separate positions. There are various options for ISO and other keys.

Firmware
The firmware file for flashing can be found in the folder. As this pcb uses a STM mcu, you will need to hold the boot button before plugging in the pcb. Then use qmk toolbox to flash (you don't need to select an MCU, just the firmware file').
Disclaimer
This PCB has been fully tested and is confirmed to work. However, no-one involved in this project is responsible for any usage issues that may arise. Order at your own risk. Feel free to edit, modify and otherwise utilise these files.

Credits
big thanks to cain (mechvault) for the amazing vault35, a design that just keeps giving.
thanks also to jlw_ for the inspiration and support with this silly project. To galvy for their work on other community pcbs and the work that I could draw from. To chronomap for help with the KLE. And to max.yw, Ha Ha Ha and ottimo for name suggestions!!!! :big heart:
and finally big thanks to summerqm for their work on the silkscreen!!!
As always big thanks to the whole 40s keyboard community!

Questions
How big is the Hhkb universal PCB?
It measures 209.7 × 76.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hhkb universal use?
216 parts, built around the 74AHCT1G125SE, ASMD1206-150, PRTR5V0U2X and SKQGABE010. 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 Hhkb universal KiCad files?
From the calvin-mcd/universal-vault repository on GitHub, at the commit this page was made from: the board is Project/hhkb universal.kicad_pcb and its schematic Project/hhkb universal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hhkb universal design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
