About the Freaku4X PCB
Freaku4X is an open source PCB design by ChrisChrisLoLo, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 190.5 × 95.3 mm, with 86 components from 8 distinct parts.
Other key parts include the ProMicro. By type, the board carries 44 switches, 40 diodes, 1 IC and 1 LED.
It belongs with the keyboards and displays & leds designs in this gallery.
From the project
A 4x10 ortholinear keyboard with a Knob and an LCD
A 4x10 ortho keyboard with a knob and OLED. It embraces the excess minimalism of the key count, and embraces the excess extravagence of a knob and oled screen. It also has a lower profile than your typical 4x10 orthos, since the microcontroller is facing upwards rather than downwards.
With that said, this keyboard in it's current form is usable with some amount of tinkering
