About the Barnacle shell PCB

Barnacle shell is an open source PCB design by floookay, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 343.2 × 114.4 mm, with 209 components from 8 distinct parts.

By type, the board carries 61 LEDs, 61 diodes, 2 connectors and 2 switches.

It belongs with the keyboards designs in this gallery.

From the project

The barnacle is unibody ortho keyboard with an Alice-like split on the pinky columns, a fixed layout that's compatible with keycap base kits and a modular middle piece.

The shell has a fixed layout with hotswap sockets as well as RGB underglow und per key RBG leds.

You can use any core pcb with a shell. They are smaller than 100mmx100mm so it's relativly cheap to get a small batch made.

This is a great starting point if you want to experiment with different layouts and don't care too much about hot swap ability.

The following configurations are supported: - 9 keys - 3 keys and a encoder with a big knob - 3 keys and a 0.96"/1.3" OLED screen - 2 small encoders, 1 key and a 0.96" OLED screen - a central encoder with the biggest knob
