Status and perspectives of large PMT electronics of the JUNO experiment

In this work, after a brief introduction on the JUNO experiment, the requirements of the JUNO electronics will be pointed out. To fulfill all the requirements a new scheme, called 1F3, for the JUNO electronics was proposed on July 2017. In the 1F3 scheme the voltage divider will be directly connected and potted with the PMT. The signal, coming from the base, will be connected to an electronics underwater box in which there will be the HV voltage supply units and the processing electronics. The current status of all the JUNO electronics boards (GCU, ADU, power board, HV units and BEC) will be described.
