Laurent Fiack contributed hardware layout improvements to the AresEnsea/2425_Projet2A_AresCFR repository, focusing on refining PCB designs for the Servo and MultipriseXT60 modules. Using KiCad and leveraging his expertise in electronics engineering and PCB layout, he corrected the Servo LF footprint to ensure reliable servo control board operation and enhanced the MultipriseXT60 footprint by adjusting mounting holes, XT60 connectors, and layer visibility. These updates aimed to improve manufacturability, reduce assembly errors, and streamline the transition from prototype to production. Laurent also updated documentation and review processes to support future hardware iterations, demonstrating thoroughness in both design and validation.
