kicad
holds the kicad project / gerber files for the board, and Power_dist
holds the code running on the microcontroller that actually does the
hot-swapping.
The BOM holds all the internal component references that are in the kicad project i.e. component '1,1' is a 102k 0603 resistor.
The datasheet for the board holds some useful information about the board capabilities and issues.
