I have finished the layout for the charger. I initially started the layout realizing that I needed to change the placement of the programmable regulator. Overall, I am happy with the overall placement and layout. The high power path is very short and clean from the USB C connector, through the fuse, to the regulator, then from the regulator to the output FET and XT60 connector.

The overall size ended up being 59mm x 47mm. Eventually I will need to design and 3d print a case.

I have sent the outputs to a few different places for prototypes. Next step will be ordering PCBAs and writing firmware. I purchased a couple of STM32F0 dev boards to get going before the boards show up.
