The Jiangmen Underground Neutrino Observatory (JUNO) is a large neutrino detector currently under construction in China. JUNO aims to determine the mass ordering and perform leading measurements detecting terrestrial astrophysical neutrinos over wide energy range, spanning from 200 keV several GeV. Given ambitious physics goals of JUNO, its readout electronics has meet specific requirements, which motivated thorough characterization described this manuscript. time synchronization among modules was found exceed by few ns theoretical expectation, as consequence non-optimal data taking conditions. However, system showed an excellent stability long periods, ensuring that any offset could be calibrated out at beginning taking. maximal deviation linear charge response 1.1% for high gain ADC 0.8% low ADC. In JUNO-like environment, i.e 40 m underwater, recorded FPGA temperature complied with reliability standards JUNO.
