Backplane Architecture Requirements

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 able to function independently to the best of its ability	Allows computer to be in modular configurations depending on flight needs
	The backplane shall route power to every board	Boards need power
	The assembly (backplane and at least four modules) shall be able to fit within a 3U cubesat	Extra points for 3U cubesat payload
	The backplane architecture shall define a standard width and height for each module	Easier to mechanically integrate
	The backplane shall survive launch operations	A flight computer should be able to survive a flight
	Modules shall be individually mechanically accessible	Speeds up prototyping/troubleshooting/repair
	The modules shall be drop-in interchangeable	Speeds up prototyping/troubleshooting/repair
	Each module should limit the amount of external I/O	Prevents a rats nest in the avionics bay/payload
