1. An electronic module for generating light pulses, comprising:
an interface card, having a first and a second side opposite to one another;
a lighting module, having a front side and a back side, housing one or more emitter devices that emit the light pulses, the emitter devices having a common biasing terminal on the back side and respective one or more dedicated biasing terminals on the front side; and
a driver module, operatively coupled to the lighting module, configured to generate biasing signals of the one or more emitter devices in order to control generation of said light pulses,
wherein:
the interface card has, at the first side, a recess provided with an electrical contact pad on a bottom of the recess, a through via, which forms an electrical connection towards the first side, and a conductive track, which electrically connects the electrical contact pad to the through via;
the lighting module is housed in the recess with the common biasing terminal coupled to the electrical contact pad by a conductive adhesive layer or layer of glue; and
the driver module is arranged facing the front side of the lighting module and the first side of the interface card, and is electrically coupled to the dedicated biasing terminals and to the through via by respective regions of conductive solder paste.
