A new Trigger/GPS unit has been developed for the Extreme Energy Events (EEE) Project, that aims to study Extensive Air Showers (EAS) by using an array of more than 50 detectors, placed also at the distances of hundreds of kilometers. The unit is an evolution of the trigger and of the timestamp system used in the past, where the detection of an EAS is achieved by measuring the coincidences in time at the different EEE stations. A first group of 27 cards was produced and distributed to the detectors. The main performance of the unit will be presented, like the trigger efficiency, the dead-time and the coincidences time resolution measured on the field.
