Seven years ago, Eben Upton created the first Raspberry Pi. As Upton told IEEE Spectrum in our March 2015 cover story, the Pi was inspired in part by his childhood experiments with a BBC Micro home computer: He wanted modern kids to have a simple machine that allowed for similar experimentation. Since then, the Pi has exploded in popularity, and the fourth major revision of the Pi was released in June. Upton talked with Spectrum senior editor Stephen Cass about the Pi 4’s design, its growing commercial use, and what might be next.
