The first Raspberry Pi shipped in 2012 as an inexpensive computer to help students learn to program. The board has since sold in the millions, inspired look-alikes, and spawned a cottage industry of small companies developing components and connectors.
In the speedy growth, Raspberry Pi hasn't lost its primary educational focus. Next month, the book "Learning Computer Architecture with Raspberry Pi," written by Upton and Jeffrey Duntemann, will be released. It will provide an in-depth look at the Raspberry Pi hardware architecture and will be a reference book for students and hardware enthusiasts.
"We're still having fun. When we stop having fun, we'll stop making it," Upton said.
