The Raspberry Pi Foundation unveiled the second version of its single-board computer for hardware hobbyists. The Raspberry Pi 2 will have six times the processing power of the original and twice the amount of main memory, but it will still cost just $35 and come in the same credit-card size electronic board. At the heart of the device is a new system-on-a-chip, the BCM2836 from Broadcom.

Microsoft has also announced that a free version of Windows 10 will be available for Raspberry Pi devices.
