OpenHornet MCAD Model

These links will allow you to download a local copy of the OH MCAD model, for reference or so you can modify things for your personal pit. If you would like to contribute to the raw MCAD, talk to Noctum in the OH Discord. You will need to prove a basic level of proficiency and be known within the discord community before access will be granted.

[!NOTE] These links will download the latest & greatest (most likely in development and unstable) MCAD. Always verify fusion parts against release package manufacturing files prior to use, and they are used at the user's own risk.

Branches

  • master branch is the stable release branch which represents the last release.
  • develop is the latest working branch that will become the next release. It may or may not be functional as is.

Questions

How big is the UFC Function Select PCB?

It measures 115 × 14.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the UFC Function Select use?

44 parts, built around the WS2812B-2020 and B3F-1026. 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 UFC Function Select KiCad files?

From the jrsteensen/OpenHornet repository on GitHub, at the commit this page was made from: the board is ECAD/PCBs/Functional PCBs/UFC_Function Select/UFC_Function Select.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the UFC Function Select design in my own project?

Its repository states no licence, so its author keeps all rights: ask jrsteensen before reusing the design.
