Raspberry Pi is a credit card-sized desktop computer that has won over millions of hobbyists. It just got a big upgrade: The first major new edition of Raspberry Pi since February 2016 launched Monday, promising faster speeds and support for more modern devices.
Raspberry Pi is an old school: It looks like a raw piece of hardware with a bunch of outputs that hobbyists use to build games, robots, music, and digital art. In the past seven years, people have gotten creative with Raspberry Pi projects. One team of inventors built a private cellphone network by connecting a Raspberry Pi to a radio interface. Another took readings from sensors to check the weather and air quality.
