@Bjarke-Freund-Hansen I've found https://github.com/OnionIoT/Onion-Docs/tree/master/Omega2/Documentation to be quite useful.

Hi @Kit-Bishop, The power jack is indeed angled on the Arduino Docks, although the pins are more or less straight; this is also the same case with the jack on the Servo Expansion. This seems to be part of the manufacturing process, but beyond that I can't say much (unfortunately I am not the hardware designer :() The angle is given by the 2.5 degree dimension on page 5, area D6, but from the samples I see it can vary about a degree or so. I will revise the Arduino Dock drawing with clearer dimensions and notes on this when I release the Servo Expansion later this week. Thanks for pointing this out!
