Eurokastle has all the functionality of the Kastle 1.5 with some tiny amendments to fit the Eurorack format. OSC mode and Rungler mode may be changed via switch instead of patching cables and you only have one input/output per functionality instead of 2 or 3 on the desktop synth. Though it has a Waveshape CV attenuator which is not available on the original Kastle.

It runs on regular Eurorack power supply.
