-So you are thinking about building a Beaglebone cape? Awesome! There are a lot of reasons to make a cape other than the fact that you will be able to implement almost every functionality you can think of all on one PCB. In 2012, beagleboard.org and circuitco held a [http://beagleboard.org/capecontest Beagle Cape competition] and gave the top three design entries $1000 dollars plus lifetime royalties on sales of the cape on circuitco. You could also try to get your cape licensed and sold by Adafruit, Sparkfun, or other DIY websites separately. Good Luck!

Even if you just interested in a fun DIY project, capes are an awesome way to learn a lot about circuit design and embedded systems. Good Luck!

−	Really the best advice from one Rose student to another is to start asking questions. The lab techs at Rose-Hulman are incredibly helpful if you are respectful. Mark Crosby is the man to ask if you need a PCB printed. After you believe that your circuit is correct, print as many PCBs as needed until it works correctly. At Rose, you are only able to print a maximum of 2-layers on a board. If you want to print more than that, you will have to send your PCB to a company to get it printed. The cheapest printing that I found in my time at Rose was at 4pcb.com. They can do almost anything and can get the board back to you in as little as 3 days if you pay for the expensive shipping.	+	Really the best advice from one Rose student to another is to start asking questions.

−	;	+	== The Physical Layout ==
		+	Laying out a PCB can be incredibly difficult. Understanding whether you want 1, 2, or 3 layer boards, how thick should the traces be, how close should the components be placed together, and more are often incredibly overwhelming at first. I cannot stress enough how helpful it would be to attend a PCB workshop that Dr. Simoni holds. He usually has at least one a year. If you cannot make it to a workshop, there are still plenty of resources that you can use to quickly design a PCB.
		+	*Ask Dr. Simoni for his PCB videos. They are not operational currently on the internet, but I believe he still has copies of the videos on his computer
		+	*http://www.expresspcb.com/expresspcbhtm/tips.htm has tips on PCB layout. Definitely a must read for any PCB newbie.

-After prototyping, you know where each of the wires is to be routed. The next step is to connect all of the components together in your CAD program of choice. There are excellent circuit layout examples to follow in both OrCAD and Eagle. Whichever program you use, a trick you can use is to find capes that use components in them that you are using in your design. Find the capes at the links below and download their respective OrCAD or Eagle files and find pads and footprints for your design. If you do this, make sure to reference the design that you used. Otherwise, pads and footprints can also be found by googling the respective part: "eagle footprint msp430"
