SN_CROB board is the common Control and Readout Board for the Calorimeter and Tracker Front-end electronics of the SuperNEMO experiment. SuperNEMO is the next-generation experiment based on a tracking plus calorimetry technique. The demonstrator is made of a calorimeter (700 channels) and a tracking detector (6000 channels). These detectors front-end electronics use an unified architecture based on similar crates. SN_CROB board gathers the front-end data from the calorimeter or tracker FEBs and sends them through Ethernet link to the DAQ. It extracts the Trigger Primitive from the front-end data and sends them through serial link to the Trigger Board.
