The KM3NeT Collaboration is building a neutrino observatory in the Mediterranean Sea, by installing thousands of optical modules distributed over a seawater volume of more than one cubic kilometer. These modules host acquisition electronics responsible for reading out 31 photomultiplier tubes. This contribution offers an overview of the KM3NeT acquisition electronics, emphasizing recent upgrades, ongoing developments, and reliability enhancements. The presentation addresses reliability improvements through theoretical FIDES analyses and practical HALT evaluations. Using the White Rabbit protocol, the clocks in the optical modules in the large-scale infrastructure are synchronized with a precision of 1 nanosecond.
