Instructions
To build an Architeuthis dux, you need the following:
- 2 pro-micro controllers (Elite-C or Pro-micro C)
- 2 PJ320A audio jack
- 1 male-to-male TRRS cable
- 34 Kailh choc v1 switches and keycaps
- Rubber feet or bumbers for the bottom
- Optional: low profile socket with Mill-max pins, or budget socket pins with round pin headers
Note: Architeuthis dux is a double sided PCB so controllers face down on the left and face up on the right.
QMK Firmware
To build the QMK firmware, run:
qmk compile -kb a_dux -km defaultParts

Questions
How big is the Macro3 PCB?
It measures 95.6 × 40.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro3 use?
9 parts. 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 Macro3 KiCad files?
From the filterpaper/split_pcbs repository on GitHub, at the commit this page was made from: the board is macro3/macro3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask filterpaper before reusing the design.
