New (v0.44) boards arrived

A project log for Huvud, a 3D Printer Tool Head Controller Board

World's smallest (42x42mm) 3D printer controller board for use on a direct drive hotend. Made to run Klipper firmware.

New boards arrived!

The ripple on the 3.3V line is now at the expected 30mV with the TPS54308 controller. Very good! I'll test with a TPS54302 in a few days when they arrive. The '302 is $0.50 cheaper than '308 even if it has more fancy power saving features. 

Now for the horrible task of hand soldering the TMC stepper drivers. Not an easy task for an unskilled solderer like myself.

The board should be ready for volume production now. I just need to re verify that everything works as intended and push the boards to their limits.
