>4 layers
That's quite the jump for a noob. Would you mind sharing how you learned to produce such advanced output so fast? I mean my first ~50 PCB we're still just 2 layers.
Edit: nvm I just saw the journal.
It's also just double the price, so I can get 4 layer boards for like $8 from JLC and it just makes everything much more easily.
You still do want to build up to it though, I made a macropad, then a keyboard, and then made this, so it's definitely not just an immediate jump, but I built those 2 projects within the span of a couple months!
The Mini Sparkle is a 4 layer and available on their github https://github.com/adafruit/Adafruit-Mini-Sparkle-Motion-PCB
There are many more available at OSHWA : https://certification.oshwa.org/list.html
