We all know the BeagleBone Black is pretty great, but wouldn’t it be nice to create personal capes based on your needs? The SparkFun BeagleBone Black Proto Cape is a great way to prototype or design custom capes and provides you access to all gpio pins available on the BeagleBone Black. The Proto Cape easily mates with a BeagleBone Black and gives you a large prototyping area, two red LEDs for user applications or debugging, and access to a blank EEPROM that is great for storing pin configuration data.
Each BeagleBone Black Proto Cape offers plenty of space to prototype with .1" spaced through-holes. There are two power buses provided along with ground connections on both sides of the board. With this cape you should have no trouble designing and creating whatever kind of add-on you would like to be attached to your BeagleBone Black.
Note: This cape does NOT include headers, we want to give you the option of choosing between which style fits your needs. 2x23 Pin Headers can be found in the Related Items section below.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I like the layout of the board, but something that isn’t really clear is that the default EEPROM address could conflict with other capes. In particular, I’m referring to the 4.3" 4D systems LCD Cape. The documentation I found was that the addresses shouldn’t conflict with each other (Proto Cape 0x57, LCD Cape 0x54). But, when these two capes are put together, the LCD Cape doesn’t work. Suspecting a EEPROM address conflict, I shorted one of the address pins on the Proto Cape, and now it works. So, regarding the documentation, YMMV.
Aside from that, this cape works fine, and does what I want.

Mechanically and electrically good quality, but support somewhat lacking.
This product will serve well as a primer for the buyer to learn about developing BBB Capes from the ground up.
But if the intention of the purchase was to use this product as a tool to clean up BBB wiring and move rapidly toward a specific goal, the documentation is inadequate for this purpose.
An email to SFE Support resulted in a rapid response with a redundant suggestion to read the Hookup Guide.
So, “Okay”, but no better.
Sure, we can Google all day long and eventually find some cogent and complete information, but that means many customers are forced to repeat the work SFE could have done ONCE to find and provide pertinent URLs.
Hi, Proto boards can be used to build up any circuit or design that you can think of. Our docs go over setting up the board to plug into the BBB, but for details on a specific use, you will need to do some research on that subject or project goal. Happy hacking
My team has a few boards of a first-iteration custom-designed cape, on which we did not include the EEPROM (an oversight on our part!). We used this cape as a retrofit add-on to this custom board to give it self-ID capability, as well as to store calibration data. Slick!
