Abstract
Printed circuit board comprising two power supplies V.sub.1 and V.sub.2 and a ground (GND), and a plurality of modules among which at least one module supplied by one of the power supplies can be replaced by another pin-compatible module supplied by the other power supply, each power supply being supplied in each case by a circuit including a ferrite connected to the power supply and a capacitor connected to the ground in order to filter the high frequency signals due to the switching operations in the modules. The board comprises a first area (24 or 24') having a first and a second terminals which is dedicated to a first ferrite to be connected to one power supply by means of its first terminal, and a second area (26 or 26') having a first and a second terminals and being dedicated to a second ferrite to be connected to the other power supply by means of its first terminal, each area including a connecting means for connecting the second terminal associated with the area to the footprints of the module.
