One design goal is to easily integrate new components without needing to revert to a breadboard design. These components should mainly be COTS (Custom-Off-The-Shelf) goods for easy and cost-efficient sourcing. A detailed overview is provided. These integrations can result in direct on-board implementation or require additional PCB designs available in the available in the Hardware Repository.
