I noticed that my latest Hellen64b boards from JLC had U1 populated. Looks like JLC has a huge amount of stock now. 17k.

https://github.com/rusefi/alphax-2chan would be the first universal board based on Hellen framework. Only two channels and only 24 pins on that one, a slightly larger version with four channels would follow.

As is Hellen One uses EOL Python 2.7 and that's not great.
A big part of this is would be that amazing gerbmerge which is a huuuuuuge mess of forks

@andreika has migrated gerbmerge and the whole framework to Python 3
https://github.com/andreika-git/hellen-one/issues/24 is still waiting for a hero
@ZHoob2004 and
@andreika are taking Hellen One into the fancy Docker universe! See

New Mega-MCU module is sooooo close! From what we have learned with the dozen (yes, it's already a dozen!) of hellen boards we've made added more stuff right into the MCU module - it now comes with SD card, reset/dfu buttons and even analog multiplexers
Power supply would get the same treatment next.

Double-sided Mega-MCU and double-sided power supply module, just look how much free space we've gained!

Sorry I am missing the humor of that question right below a photo of a board with stm32f407zg?

this is what surprised me, since stm32h743zit is indicated on the diagrams, and for what type is the compiled firmware then?

stm32 is pin compatible between F4, F7 and H7 at least in 144 and 176 packages - we assemble different boards with different chips in light of chip shortage and prices and not complete support of H7 in rusEFI.
In
https://github.com/rusefi/rusefi/tree/master/firmware/config/boards/hellen folder
https://github.com/rusefi/rusefi/blob/master/firmware/config/boards/hellen/hellen81/compile_hellen81.sh would target ARCH_STM32H7 while all other boards currently target ARCH_STM32F4
https://github.com/andreika-git/hellen-one/issues/249 created for root cause of your legit confusion.

KiCad 7.0.6 was just released with David's improvement and we now have automated gerber export toolset! This would save a lot of human hours and hopefully reduce a chance of error, really exciting framework progress!

Just updated hellen-one documentation to reflect the reality of docker-based github automation
https://github.com/andreika-git/hellen-one/tree/master#tldr
https://github.com/rusefi/hellen-example is the skeleton project to jump start your hellen project repository.
