Overview
Squall pcb is an open-source printed circuit board by mattc-kb, from the mattc-kb/The-Squall repository on GitHub. It is a 2-layer board of 115.4 × 90.8 mm with 48 parts on 71 nets, routed with 929 tracks and 90 vias.
Its parts include 18 diodes and 18 switches.
README
README.mdThe Squall v1.0
Wireless split keyboard build based off of the Tempest which in turn is based on the Temper and Chocofi.
I wanted a splay for the outer columns, but a slightly more agressive stagger than the Tempestv2 while retaining the thumb cluster placement of the Temper and Chocofi.
Included in the repo are the ergogen config and footprint files as well as the Kicad output and gerbers for both the PCB and the plates.
Bill of materials:
36 smd diodes 36 Choc hotswap sockets 2 NiceNano / nRF52840 BLE controllers 2 JST sockets 2 smd power switches 2 reset switches
Assembly:
Soldering of the jumpers for the controller, NiceView and the power connector is done on the back of the board. The same side as the sockets and diodes. The power switch is also intended to be mounted on the underside of board.
Firmware:
I have loaded and I am currently using Corne firmware successfully on this board.

Questions
How big is the Squall pcb PCB?
It measures 115.4 × 90.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Squall pcb use?
48 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 Squall pcb KiCad files?
From the mattc-kb/The-Squall repository on GitHub, at the commit this page was made from: the board is kicad/squall-pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Squall pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask mattc-kb before reusing the design.
