Welcome
Do you own a Raspberry Pi 2?
It’s the latest flagship Pi from the
Raspberry Pi Foundation and is
six times faster than the older
models – making it perfect for projects that
were previously out of reach. This issue we
tell you everything you need to know about
the board itself and help you switch over
from an old Pi, and then we show you how
to turn it into either a home theatre PC or use
it as a full-blown desktop PC – it really is that
powerful! And do you remember the robot
that we built together way back in issues 2
and 3 of
RasPi?
Well, check out the kit from
Dawn Robotics that’s reviewed towards the
end of this issue – it’s a pretty ideal present
for someone this Christmas!

What is the Raspberry Pi 2?
Still confused over what the new version of the
Raspberry Pi means to you? We’ll fill you in
Q There is another Raspberry Pi then? Is it another
update, a brand new thing or something entirely
different? I’m getting a bit confused already!
A
This time it’s the Raspberry Pi 2 Model B – basically a
brand new Raspberry Pi.
Q Basically a brand new Raspberry Pi?
A
Well the thing that truly counts, the thing that makes it
a Raspberry Pi, is the chip that powers it. The Broadcom
BCM2835 chip is literally the core of the original Raspberry
Pi, the system-on-a-chip that had the ARMv6 700 MHz
processor and the VideoCore graphics chip. This was what
was on the compute module from a while back, along
with the 512 MB of RAM present in the Pi Model B v2 and
B+. Anyway, this chip has been updated and the RAM
increased, which is what really makes it the Pi 2.
Q What is the new chip about, then?
A
The BCM2836 is a slightly modified version of the 2835
– the main difference is that it now has an ARMv7 quad-
