Not so modest 
We all cooking with water, only
Without brainstorming, everybody will make the same mistakes for itself. Everybody can learn much faster with discussion about schematic and PCB design.
I think, it exist more people with software skills, as with elektronic development skills.WLED is open software and it’s also fair, to give back a hardware solution also for free.
It must not be perfect, but with brainstorming, maybe it will be perfect 
I have developed a ESP8266 based controller, what be able to solder with RS485 linedriver or 2 levelshifter, or 4 logilevel MOSFETs. The PCB is universal.
Maybe we can merge ouer projects to a solution with ESP32.

My PCB isn’t perfect, i’d forgot some lines and fixed it with wirepices. I can fix my design, but i don’t need much more, like 10 controllerboards
I work with a old Version from Eagle
