Hello - please find the initial draft of the evaluation board for Caravel attached. The specification is for a two-board system - a main board assembly that is common from shuttle to shuttle, and a daughter board assembly that hosts the users package part and provide basic support functions. The daughter board has minimal components and can be assembled onshore with a quick-turn. It has castellated holes so it can be hand-soldered to the main board or a user’s own PCBA.
