About the Fract PCB

Fract is an open source PCB design by skarrmann, published on GitHub under the MIT license. It is a 2-layer board measuring 180 × 75 mm, with 72 components from 6 distinct parts.

Other key parts include the nice!nano. By type, the board carries 34 switches, 34 diodes, 1 IC and 1 connector.

It belongs with the keyboards, iot & wireless and dev boards & breakouts designs in this gallery.

From the project

34 key wireless ortholinear keyboard with self-encasing PCB.

Fract is a 34 key ortholinear keyboard, powered by a bluetooth-enabled Pro Micro compatible dev board.

It uses Choc v1 keyswitches with 18mm x 17mm spacing.

The goal of this design was to build a simple pocketable keyboard out of PCBs.
