INDRA is a 4 π charged particle detection array in use since 1993 for the study of nuclear collisions at bombarding energies from a few 10s to a few 100s of MeV/nucleon. Originally equipped with custom electronics using the VXI standard, the entire acquisition system was recently upgraded to a fully digital system using commercially-available modules supplied by mesytec GmbH & Co. KG. At the same time, both low and high voltage supplies and all cabling and signal routing outside of the reaction chamber have also been replaced. The new electronics were used for the first time in 2022 in an experiment at GANIL coupling INDRA with 12 blocks of FAZIA telescopes placed at forward angles. The full details of the upgraded system, and the resulting improvements in performance, stability, dead time and identification capabilities are presented in this article.
