Atom interferometers with two species have been used to test the Einstein equivalence principle (EEP). To improve their precision, long evolution times in the interferometer are required. This can be accomplished with degenerate quantum gases and extended free fall in space. In order to increase the free evolution time the apparatus is moved into a microgravity environment. The BECCAL experiment will, for the first time, enable a multitude of experiments with a dual species atom interferometer in space where BEC's freely float for seconds. Operation on the ISS poses strict requirements on mass, size and operation safety of such an apparatus. To comply with these specific restrictions and the requested scientific capabilities, several payload elements will be new developments based on our experience from other space missions like the MAIUS 2/3 Sounding rocked missions. In this poster we show the overall design of the electronic components and the progress in our work.
