From the project

Split columnular stagger 4x6 keyboard

A split ergo 4x6 keyboard designed by Keith Wade.

Designed for use with the [nice!nano][nicenanoDocs] USB-C Bluetooth Pro Micro replacement but also works with any Pro Micro compatible controllers like the Elite-C.

Inspired by the [ErgoTravel][ergotravel] keyboard designed by @jpconstantineau.

- Split - Columnular stagger - Wireless option - Hot swap MX switches - Reversible PCB

Keaboard rev1: common questions

What microcontroller does the Keaboard rev1 use?

The Keaboard rev1 is built around the ProMicro, from the AVR/Arduino family.

How big is the Keaboard rev1 PCB?

The Keaboard rev1 measures 141.9 × 93.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keaboard rev1?

55 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keaboard rev1 design files?

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

Can I use the Keaboard rev1 design in my own project?

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

Can I test firmware for the Keaboard rev1 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.
