Interferometry experiments with ultra-cold degenerate quantum gases under microgravity conditions offer possibilities to test fundamental laws of physics to unprecedented precision. The MAIUS-2/3 sounding rocket missions are planned to explore dual-species atom interferometry in space. Operation on a sounding rocket poses strict requirements on the mass, volume, reliability and robustness of the payload and the system needs to operate autonomously. Based on our experience from the predecessor mission MAIUS-1, we improved our electronics to match the needs of a mission with two species, for example we developed automated electronics for microwave driven evaporation techniques with two species. We downsized the electronic components used for MAIUS-1 to fit hardware for dual species operation in an apparatus of the same size. With this poster we present our current progress. The QUANTUS/MAIUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number: 50WP1431.
