Have you ever wanted a Raspberry Pi but thought that £16/$25—roughly three packs of cigarettes—was a little exorbitant for a complete computer capable of running Linux? Well, I have good news: the Raspberry Pi Foundation has just released the Pi Zero, a single-board computer that costs just £4/$5.
The Zero isn't just some add-on module or something like that, either—it's a full-fledged member of the Raspberry Pi family. The Zero is powered by a Broadcom BCM2835 (the same SoC in the Raspberry Pi 1), with a 1GHz ARM11 CPU core. There's 512MB of RAM; a micro SD slot; two micro USB sockets (data and power); and a mini HDMI socket that can output at 1080p60. Perhaps most importantly, though, the Zero has 40 GPIO pins with the same pinout as the Model A+, B+, and 2B. There's also some headers for RCA composite video out.
The ARM CPU, according to the Foundation, is 40 percent faster than the original Raspberry Pi 1 Models A, A+, B, and B+. The SoC, plus the RAM and the standard GPIO layout, means that the Zero has enough chutzpah to run Raspbian. It should also be fully compatible with most existing Raspberry Pi software and projects.
