Gotogen Hardware

Protogen, the Go way. This repository is the entrypoint for hardware devices.

Highly volatile during active development. For ease of my own development, there are replace directives in go.mod to use relative paths for the related modules (go.work wasn't working for me). I will attempt to keep all the repositories up to date. You will need to either remove the replace directives, or have all the repositories checked out next to each other.

Questions

How big is the Gotogen matrixportal PCB?

It measures 134 × 105.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Gotogen matrixportal use?

28 parts, built around the PCF8574T. 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 Gotogen matrixportal KiCad files?

From the ajanata/gotogen-hardware repository on GitHub, at the commit this page was made from: the board is kicad/gotogen matrixportal.kicad_pcb and its schematic kicad/gotogen matrixportal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Gotogen matrixportal design in my own project?

Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
