1. A module fora digital display panel, the module comprising:
an electronic board whose first face presents a network of light emitting diodes arranged in rows and columns with a substantially constant pitch;
a chassis mounted on a second face of the electronic board, opposite the first face; and
a water permeable connector mounted on the second face of the electronic board;
wherein the chassis has a base surrounding the water permeable connector, a top part of the base having at least one groove wherein a seal is inserted, and wherein the module has a power supply box with a continuous voltage connector surrounded by a ferrite and inserted into the water permeable connector, with the power supply box being attached to the chassis so that a bottom plate of the power supply box cooperates with the seal of the base to ensure sealing around the water-permeable connector and the continuous voltage connector of the power supply box.
