AB  - Quantum bit control systems using room temperature electronics provide universities and research institutions a cost-effective entry into quantum computing. Various approaches address the need for straightforward qubit controllers, particularly those based on AMD's next-generation RFSoC FPGA, which integrate adaptive SoCs with internal ADCs and DACs. As superconducting qubit architectures advance to incorporate flux elements for direct Z axis control and the number of qubits grows, the demand for high-quality and numerous control channels increases. This paper explores the requirements for integrating and expanding the QiController electronics from Karlsruhe Institute of Technology. The new system includes up to ten cards capable of driving a total of 240 direct flux lines. Our joint system design leverages the modularity, scalability, and thermal management of the industrial Standard ATCA, ensuring robust performance and ease of maintenance in this multi-FPGA setup. Initial unit tests of the electronics show improvements in noise levels and quality, suggesting that future verification on real qubit devices could establish this approach as a viable solution for scalable room-temperature control hardware.
