Title: The electronics readout and data acquisition system of the KM3NeT neutrino telescope node

The KM3NeT neutrino telescope will be composed by tens of thousands of glass spheres, called Digital Optical Module (DOM), each of them containing 31 PMTs of small photocathode area (3'). The readout and data acquisition system of KM3NeT have to collect, treat and send to shore, in an economic way, the enormous amount of data produced by the photomultipliers and at the same time to provide time synchronization between each DOM at the level of 1 ns. It is described in the present article the Central Logic Board, that integrates the Time to Digital Converters and the White Rabbit protocol used for the DOM synchronization in a transparent way, the Power Board used in the DOM, the PMT base to readout the photomultipliers and the respective collecting boards, the so called Octopus Board.
