Got a Raspberry Pi and want to explore i/o options while maintaining the overall footprint of your project? If the answer is yes, then checkout maker Joe Walnes‘ Pi Crust breakout board. With convenient headers and clear labels, the Pi Crust is the a great choice when you want to cram as much as you can into a tight enclosure. But don’t expect to buy one off-the-shelf. If you want a Pi Crust, you’ll have to order the parts and assemble it yourself.
