When I was updating the PCB I also fixed one more issue that I found during testing. For some reason I was not able to reduce the power draw of the ATSAM4S2BB to a level I would like it to be so I changed back to the same mechanism as the previous version where the hardware button controls the enable line of the power regulator and the microcontroller takes over when it turns on.

I also found another issue but I decided that was oke for now. It looks like the charger IC I dediced on cannot handle the current draw from the SD-Card when it does a write without a battery. Maybe Ill update this in the future but for now doing nothing on it.

The PCB house I was using changed their prices quite a bit. Went from 50 euro to 70 euro for 5 boards even when I went from 8 layers (because I was lazy) to 6 layers, so decided to try the panneling service for once. For some reason it still costs the same but will get 50 bords now instead of 5. Will see how it goes.
