The KM3NeT Collaboration is constructing and managing two deep-sea neutrino telescopes on the
Mediterranean Sea floor. These telescopes are composed of networks of light detectors enclosed
in pressure-resistant glass spheres, known as digital optical modules. Each module contains 31
photomultipliers, each with a 3-inch diameter, along with acquisition electronics. The detection
units consist of vertical strings where these digital optical modules are mounted. In the initial
construction phase, several dozen detection units were manufactured incorporating over 20,000
photomultipliers that are actively collecting data. Upon completion, the telescopes will feature
more than ten thousand digital optical modules synchronized at the level of the nanosecond,
forming one of the most intricate operational and synchronized networks globally. This work
provides an update on the current status of the Digital Optical Module and DU Base acquisition
electronics, highlighting upgrades to key components, such as the central logic board and the base
module backplane.
