Turns out making a 3D printer main board is not that easy. I must say I went into it with too much "not thinking" and too much enthusiasm. However, I got some knowledge, and a new idea that can be realized faster than the whole main board.
There it is in KiCad. I can't understand why it has so much VDD pins. I guess i can just copy the capacitors on those from someone else. 12 * 100nF caps. Guess one for each damn pin. Just will take too much space on the board. What follows
In order for Marlin firmware to work properly on my imaginary main board I'm building. Turns out there is a file in a Marlin GitHub repository that has pre set pins for certain popular main boards that use H7 as their brain. One of those is a BTT
Well the task of making a main board is incredibly complicated, that's why it needs to be as simplified as much as possible. The schematic of Ender 3 motherboard is a good reference I feel. Because they wanted to cut costs everywhere they could. That includes a main
