Hello, here's a 3D rendering of the board and also a mock-up of the 9 to 15 pin dsub adapter. This is my first time routing a PCB, if someone has experience routing PCBs please let us know if you have any suggestions or feedback. More specifically, should certain circuits (power, ground, Atari I/O, I2C, GPIO) have more direct routes than others, greater clearances, not use vias, etc?
