OBC Flight Model Requirements from Mech

(1) Hard constraint on that 90mm by 90mm for the PCB boards in case you forgot; height constraint is still consistent with PC 104 standards; (2) sorry if you already said this somewhere, but can we have your layout requirements for your parts (eg EPS will either have on-board batts or batts on mounts, or comms need their board near the antenna); and (3) can you make sure for the mass budget that the mass is per item not total mass. Just reply when you can

How to Gator Done?

1. Review OBC Rev 1 Block Diagram —> define what we want on this first one
   1. USB powered? More devboard-like than flight ready?
2. Starting on implementation
   • [ ] Daniel starts on actually implementing the microcontroller and making schematic for it
   • [ ] Kiran starts on the LDO (or Buck converter?) for 3V3 to 1V2
   • [ ] Kiran will also try to compile some electrical integration information —> figure out what pins to break out to what headers
   • [ ] Finalize schematic and get internal review

OBC Rev #1 Changes Required
