Atom interferometers with two species of cold degenerate quantum gases have been used to measure the Eötvös ratio. Ground-based experiments face limitations due to the trajectory of atoms within the confined space of the science chamber, which impacts the improvement of the Eötvös ratio in the interferometer due to the limitation of the free-fall time. However, employing a microgravity environment, provided for example by a sounding rocket or the ISS, presents advantages as it bypasses the constraints imposed by the apparatus size. In order to achieve interferometers for such conditions, the development of high-precision, compact electronics that meet the required standards and safety regulations for both the ISS and unmanned sounding rockets is essential. The electronics presented in this poster were developed with our experience in the QUANTUS family projects and proved their qualification by driving the lasers and magnetic fields to create degenerate quantum gases of two species during the MAIUS-2 sounding rocket mission.
