ATmega UNI Power Shield

Notes about prototyping power shield for ATmega UNI.

1st version

Experimenting around having 3.3V and 5V from a small shield.

KiCAD schematics+PCB are on GitHub.

Generally works, but it's too thick to put any shield on the top of the UNI board, so will have to rework.

2nd version

With Power Jack removed so it can be soldered directly on a board below.

3rd version

Like 2nd version but with break-away power jack part, which did not had all the break-away holes as expected.

4th version

Like 3nd version but with working break-away holes. This time ordered using "‚ö°Blitz Manufacturing" at Aisler. Placed order on 4.11. (Monday) late in the night, envelope arrived to my postbox in Vienna today on 11.11 (Monday) = in exactly one week.
