Breakout Board Replacement for Ender 3 S1

I am working on a PCB replacement for the Ender 3 S1. After frying one of the pins, and subsequently fixing it with a bead of solder, I realized that this board is a missed opportunity to add a bunch of extra capabilities to this machine. There is enough room for some components on this hotend breakout board, so I would like to duplicate the original design, but improve upon it, adding additional features and better connectors. These tiny connectors look nice, but are less practical, because virtually nobody else uses them.
