The KM3NeT collaboration aims at the construction of a neutrino telescope with a volume of several cubic kilometres at the bottom of the Mediterranean Sea. The telescope will consist in an array of Digital Optical Modules (DOMs) that will detect the Cherenkov light originated by the interaction of the neutrinos with the matter in the proximity of the detector. In the present article it is presented the read-out electronics of the DOM, composed of PMT bases, in charge of converting the analogue signal produced in the 31 PMTs in a Low Voltage Digital Signal (LVDS); the Octopus boards, that transfer the LVDS signals from the PMT bases into the Central Logic Board (CLB); the CLB, the most complex board of the read-out system, with 31 Time to Digital Converters of 1 ns resolution and the White Rabbit protocol embedded in the CLB Field Programmable Gate Array, and the Power Board, that delivers all the power supplied need by the DOM electronics. All the DOM read-out electronics system is fully described in the present article.
