→Step 0: Product Design

== Step 0: Product Design ==
The most often skipped step in designing a PCB is the design itself. Most EE's don't take product design classes, but it's an important skill to develop. Putting together a comprehensive design will push you to answer the following questions:
* What are the functional requirements of my PCB?
* What are the major components you will need on your board to achieve that functionality?
* In what ways will these components be interconnected? (SPI, UART, I2C, CAN)
* How will power be managed on your PCB? How much power do you need, and where will it come from? How long do your batteries need to last, and what kind will you use?
* What physical and thermal requirements do you need to satisfy? Will there by high acceleration or low temperature? How will you test these factors?
* What shape/size does your PCB need to be? How will it be mounted?
* What things need to connect to your PCB? What kind of wires will you use? What kind of connectors? Will you be able to quickly integrate and de-integrate your PCB from the system?
* What failure modes could your board exhibit, and which could hurt mission success or pose a safety risk? How can you mitigate these risks in your board?
* In what ways could misuse/abuse of your board destroy it, and how can you add protections from the stupid behavior of your future self?
