An anonymous reader writes: The Raspberry Pi Foundation unveiled the Pi Zero, a new $5 mini-computer, Thursday morning. The board is the smallest Raspberry Pi yet, containing the first-gen Raspberry Pi's BCM2835 chip (safely overclocked to 1GHz) and 512MB RAM. The latest issue of The Magpi will include a free Raspberry Pi Zero and hits U.K. newsstands Thursday. The announcement came just a few days before the highly anticipated C.H.I.P. $9 mini-computer goes on sale to the public.
