About the KiboOne PCB

KiboOne is an open source AVR/Arduino PCB design by filipsalo, published on GitHub. It is a 2-layer board measuring 304.8 × 100 mm, with 137 components from 71 distinct parts.

Its main chip is the ATmega32U4-AU, from the AVR/Arduino family. By type, the board carries 63 switches, 63 diodes, 4 capacitors, 3 resistors, 1 IC and 1 crystal.

It belongs with the keyboards designs in this gallery.

From the project

Keyboard. Work in progress.

A keyboard built from the ground up to my personal preferences, using switches and keycaps from 1980s Apple keyboards. Very much a work in progress.

Must be fun to make Alps switches are nice AEK-era Apple keycaps are nice Stabilizers are the devil The width of standard ANSI shift keys is ridiculous The width of a standard spacebar is ridiculous Actually, no key really deserves to be wider than 2u The thumb is underused for modifier keys * The left-leaning stagger for the left hand on standard keyboards seems a bit silly

KiboOne: common questions

What microcontroller does the KiboOne use?

The KiboOne is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the KiboOne PCB?

The KiboOne measures 304.8 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KiboOne?

137 components, from 71 distinct parts. The full bill of materials is listed on this page.

Where can I download the KiboOne design files?

From the filipsalo/KiboOne repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the KiboOne design in my own project?

The repository has no license, so all rights stay with filipsalo. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the KiboOne without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
