Team Vision for Detailed Design Phase

During this phase, each member focused on finalizing their specific task for their internal device piece, such as heat testing for the power control board, finishing CAD models, creating test plans for each device protocol, and running simulations for the interface board. By the end of the detailed design phase, tests and simulations were successfully completed leading to more modifications to achieve individual goals.
