This thesis, supported by IUVO company’s in-house expertise, has the goal of designing and building an electronic board capable of addressing some electronic and electrical integration requirements of their lower-limb exoskeleton. This board serves as a smart button circuit for power control in a wearable lower-limb exoskeleton and aims, in some respects, to be an alternative to their state-of-the-art solution and, in others, a potential technological integration by introducing additional features. In fact, for the development of this board, the functions already implemented by the IUVO board were redesigned, remaining focused on the power control aspect, while simultaneously seeking to introduce technological innovations that could improve the product. The development process was approached with particular attention to performance, space requirements—essential for a portable product—costs, and safety for the end user. Once the technical requirements—which differed in part from the IUVO solution—were established, guiding the definition of the proposed architecture and the selection of components, the board’s development followed the workflow described in this thesis, which characterized its simulation, design, production, and preliminary validation.
