About the Avalanche hotswap PCB

Avalanche hotswap is an open source PCB design by vlkv, published on GitHub under the MIT license. It is a 2-layer board measuring 179.7 × 122.8 mm, with 139 components from 18 distinct parts.

Other key parts include the ProMicro. By type, the board carries 35 switches, 32 diodes, 32 inductors, 12 jumpers, 6 connectors and 2 resistors.

It belongs with the keyboards designs in this gallery.

From the project

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.
