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.

4 layer boards actually make it easier instead of more advanced in my opinion. You can have a dedicated ground and power plane which makes routing much simpler, and the fields are much easier to predict.

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!

For me, it helped me to look at open source hardware like adafruit's.

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
