Overview
Avalanche hotswap is an open-source printed circuit board by vlkv, from the vlkv/avalanche repository on GitHub. It is a 2-layer board of 179.5 × 122.6 mm with 139 parts on 96 nets, routed with 3,869 tracks and 391 vias.
Its parts include 35 switches, 32 diodes, 32 inductors, 6 connectors and 2 resistors. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.
README
README.mdThe Avalanche keyboard
The Avalanche keyboard is an ergonomic split keyboard with 4x6 (or 3x6 if you break off the 'digits' row) column staggered keys, 5 thumb keys, 1 additional key for the pinky (break off-able too) and 2 additional keys for the index finger (64 keys total).
Avalanche design was inspired by a number of great keyboards. You may read more about it in my very first reddit post.

Layout tester
Cut left half and right half from some piece of a cardboard, insert switches, put on the keycaps and try the layout.

Build instructions
Are here. These instructions are very brief and insufficient as a detailed build instructions for a beginner. That is why (if you are a beginner) I recommend you to also read these resourses:
Chat group
There is a chat group in Telegram, where you may chat about the project or ask some questions/help.
Firmware
- QMK.
- ZMK from our friend romones. According to him: "Keyboard works, encoders work. I couldn’t figure out lights and displays. And if you plan to use it note there is an override for a dead pin in right overlay".

Questions
How big is the Avalanche hotswap PCB?
It measures 179.5 × 122.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Avalanche hotswap use?
139 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 Avalanche hotswap KiCad files?
From the vlkv/avalanche repository on GitHub, at the commit this page was made from: the board is pcb/avalanche-hotswap.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Avalanche hotswap design in my own project?
Its repository states no licence, so its author keeps all rights: ask vlkv before reusing the design.
