| Number | Requirement | Rationale |
|---|
| The backplane shall provide a method of communication between all modules | Adding simple boards to the system should be relatively easy |
| Each module shall be self-sufficient | Adding simple boards to the system should be relatively easy |
| The backplane shall route power to every board | Boards need power |
| The assembly (including batteries) shall fit on a single sled | Two connected sleds are annoying |
| Each module should be the same size | Easier to mechanically integrate |
| The backplane shall survive New Mexico | Avionics should work where we want to use it |
| The backplane shall survive launch and Launch | Avionics should work where we want to use it |
| The backplane shall (tolerate module failures/isolate faults) |
