A data acquisition device comprising: - a casing comprising a lateral wall delimiting a cavity, - a plurality of electronic modules stacked in the cavity in a stacking direction, each electronic module having a first face and a second face opposite to the first face, and comprising a first set of conductive tracks extending over the first face, and a second set of conductive tracks extending over the second face, the first set of conductive tracks comprising at least one conductive track dedicated to the transmission of a data signal, and the second set of conductive tracks comprising at least one conductive track dedicated to the transmission of a data signal and the second set of conductive tracks comprising at least one conductive track dedicated to the transmission of the data signal and electrically connected to the conductive track dedicated to the transmission of the first set of conductive tracks via an electrical connection passage extending inside the electronic module, - one or more connector block(s), each connector block being positioned between two adjacent electronic modules (12A, 12B) of the stack to establish an electrical connection between each track of the first set of conductive tracks of one of the electronic modules and a corresponding track of the second set of tracks of the other of the electronic modules, and - a pressing member able to apply a compression force to the electronic modules, parallel to the stacking direction, the compression force tending to deform each connector block by increasing a dimension of the connector block in a radial direction, perpendicular to the stacking direction, so as to maintain each connector block supported against the lateral wall of the casing. - a casing comprising a lateral wall delimiting a cavity, - a plurality of electronic modules stacked in the cavity in a stacking direction, each electronic module having a first face and a second face opposite to the first face, and comprising a first set of conductive tracks extending over the first face, and a second set of conductive tracks extending over the second face, the first set of conductive tracks comprising at least one conductive track dedicated to the transmission of a data signal, and the second set of conductive tracks comprising at least one conductive track dedicated to the transmission of a data signal and the second set of conductive tracks comprising at least one conductive track dedicated to the transmission of the data signal and electrically connected to the conductive track dedicated to the transmission of the first set of conductive tracks via an electrical connection passage extending inside the electronic module, - one or more connector block(s), each connector block being positioned between two adjacent electronic modules (12A, 12B) of the stack to establish an electrical connection between each track of the first set of conductive tracks of one of the electronic modules and a corresponding track of the second set of tracks of the other of the electronic modules, and - a pressing member able to apply a compression force to the electronic modules, parallel to the stacking direction, the compression force tending to deform each connector block by increasing a dimension of the connector block in a radial direction, perpendicular to the stacking direction, so as to maintain each connector block supported against the lateral wall of the casing.
