Ergonomic Keyboard Generator


The project aims to provide a common configuration format to describe ergonomic 2D layouts and generate automatic plates, cases, as well as un-routed PCBs for them. The project grew out of (and is an integral part of) the Absolem keyboard, and shares its Discord server as well.

Getting Started

Until there's a proper "Getting started" guide, try getting acquainted with Ergogen by following these steps in order:


  1. Read the Documentation.

    D'uuh. They're not complete by any measure, but should give you a fairly good idea what you're dealing with here.


  2. Try one of the web-based deployments.

    Button Official    Button Unofficial

    The unofficial deployment is probably better, tbh, and will soon be replacing the official one. Choose either one, then click things, look at outputs and see if things start to make sense.

    There is no need for you to download the CLI unless you want to do one of the following:

    • Preview in-development features
    • Use custom modifications
    • Contribute code

  3. Search the ergogen topic on GitHub.

    There, you can look at (and reverse engineer) a variety of real life configs using Ergogen. Pop them into the web UI to see what they do, tinker with them and things should start to make more sense.


  4. If a question persists after all of the above, feel free to ask it over on Discord and we'll do our best to help you out.

Questions

How big is the Thumb3 PCB?

It measures 20 × 51 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Thumb3 use?

12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Thumb3 KiCad files?

From the yangit/ergogen repository on GitHub, at the commit this page was made from: the board is input/routed/thumb3.kicad_pcb and its schematic input/schema/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Thumb3 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
