Shape of things to come

The new Raspberry Pi 2

Raspberry Pi 2 on sale now for $35, featuring a 900MHz quad-core ARM Cortex-A7 CPU (~6x performance), 1GB LPDDR2 SDRAM (2x memory) and complete compatibility with the Raspberry Pi 1.

Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10. Says Eben Upton:

“I think it’s a usable PC now. It was always the case that you could use a Raspberry Pi 1 as a PC but you had to say ‘this is a great PC in so far as it cost me 35 bucks’. We’ve removed the caveat that you had to be a bit forgiving with it. Now it’s just good.”

Compared to the Model B it has:

  • More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.
  • More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
  • Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
  • Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
  • Better audio. The audio circuit incorporates a dedicated low-noise power supply.
  • Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
