Within this paper we present the design and implementation of a modular commercial off the shelf (COTS)-based brush less direct current (BLDC) power stage using gallium nitride - field effect transistors (GaN-FETs). Possible application scenarios are small mobile systems for lunar application with short and medium envisaged mission lifetime. We are giving details in the design process of the power stage and component selection process. Furthermore, mitigation techniques for radiation environment, redundancy and special electrical design considerations are covered. Detailed insights in development, design, and production of the power stage, are presented and next steps for technology readiness level (TRL) increase. The described results are based on the DFKI's outcome of the project iCOTS11https://robotik.dfki-bremen.de/en/research/projects/icots which ended in July 2023.
