Abstract
GRBNeT is a Gamma Ray Burst Neutrino Telescope made of autonomously operated arrays of deep-sea light detectors, anchored to the sea-bed without any cabled connection to the shore. This paper presents the digital and analog electronics that we have designed and developed for the GRBNeT prototype. We describe the requirements for these electronics and present their design and functionality. We present low-power analog electronics for the PMTs utilized in the GRBNeT prototype and the FPGA based digital system for data selection and storage. We conclude with preliminary performance measurements of the electronics systems for the GRBNeT prototype.

Summary
GRBNeT is a Gamma Ray Burst Neutrino Telescope that involves the development, construction and testing of a prototype for an autonomous array of deep-sea detectors, capable to operate continuously for a prolonged period of time, anchored at the sea bed without any cabled connection to the shore. One of the key features of GRBNeT is its ability to operate autonomously, without the need of a submarine cable to supply the necessary power from the shore This autonomy is achieved by utilizing locally a cluster of batteries, housed in glass spheres that provide the entire system with power. The main advantage of this feature is the cost reduction by omitting the submarine power cables to shore, while on the other hand, it creates a restriction to the detector’s power consumption Is used to handle the slow-control tasks, partitioning the system’s tasks to achieve low power dissipation
