Hi everyone,

I’m currently working on a custom module design to interface with the M5-Bus, and I’ve been evaluating a few different EDA tools to manage the footprint and schematic capture.

For those of you who regularly design your own custom HATs, shields, or baseboards for M5Stack cores, which software do you find provides the best library support for the M5-Bus headers?

My main question: If you are designing multi-layer boards for custom modules, have you found a specific tool that handles the M5Stack pin-mapping verification more reliably than others? I'm curious if anyone has a preferred workflow for ensuring signal integrity when stacking custom hardware on the Core series.

Looking forward to hearing how you all tackle the custom hardware side of your projects!
