The Einstein equivalence principle has been tested with in dual species atom interferometers. Compared to ground based experiments, the ISS provides a microgravity environment and can therefore increase the free fall time in ground based experiments. For running such an atom interferometer in a space born platform, high precision and compact electronics are needed. Strict requirements for the operation on the ISS such as operation safety and size demand new developments for several electronic components. Based on our experience from other space missions such as the MAIUS 2/3 sounding rocket missions, the new components will be designed to comply with these specific restrictions. In this poster we show the overall design of the electronics and the progress in our work. This project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for economic affairs and energy (BMWi) under the grant numbers 50WP1431 and 50WP1700.
