Questions tagged [breakout]
Breakout boards are small single-function component level boards that usually combine ICs, sensors and commonly used passive components into a package to perform a specific function. They are often used by hobbyists and provide a good way for amateurs to access SMD-class technology in a breadboard-friendly package.
