Assumptions

1. 15 total OBC PCBs (Note that PCBWay requires you to make orders in multiples of 5)
   • 5 for REV #1
   • 5 for REV #2
   • 5 for Flight OBC
2. MCU is the RM46L852
3. All components selected for the RM46-based OBC are still in stock. The components can be found on OBC Rev #1 Component Selection
4. The lower bound of the cost estimate is based on the cheapest component options. The upper bound is based on the most expensive component options.
5. Passive components and headers cost $10 per board
6. All components are purchased from Digikey
7. PCBWay is used for all PCB manufacturing
8. Only one batch of OBC revisions (such as 5 PCBs for REV #1) is ordered at a time. No other revisions or PCBs are taken into account when using the PCBWay calculator (# of boards is set to 5).
9. The costs for REV #2 and the Flight OBC is equal to the cost of REV #1
