TL,DR:

hellen-one is a toolset to produce custom PCBs by merging gerber files of known proven functional modules into trivial frame PCB with mostly just the main vehicle connector. Gerber export and gerber merging happens in the cloud, i.e. on the github server.

Step 1: fork https://github.com/rusefi/hellen-example/ repo to get github actions and meta files learn about forking

Step 2: make sure github actions are enabled/enable github actions on your fork

Step 3: replace xxx and yyy in revision.txt with name of your board. By the way we expect kicad files to be placed in the root folder of the repository.

Step 4: create youboard.kicad_pcb from proven modules using KiCAD

Step 5: push into github to trigger hellen-one gerber expert and gerber merge (that's where the hellen magic happens! for instance gerber export is taken care by export.sh script which github action would invoke automatically. Just watch for the yellow circle to turn into a green checkmark.)

Step 6: (sorry rotation only by factor of 90 degrees at this point)

Step 7: order your using fabrication files from 'boards' folder!

FAQ

Q: I do not have any files inside hellen-one folder on my PC

A: That's a problem, you have not cloned submodules. See https://stackoverflow.com/questions/3796927/how-do-i-git-clone-a-repo-including-its-submodules

Questions

How big is the Hellen1-uaefi PCB?

It measures 100 × 100 mm and has 4 copper layers, 4.62 mm thick.

What parts does the Hellen1-uaefi use?

90 parts, built around the RT-01T-1.0B. 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 Hellen1-uaefi KiCad files?

From the andreika-git/hellen-one repository on GitHub, at the commit this page was made from: the board is kicad/modules/hellen1-uaefi/hellen1-uaefi.kicad_pcb and its schematic kicad/modules/hellen1-mcz33810/hellen1-mcz33810.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hellen1-uaefi design in my own project?

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