This issue wetell you everything you need to know aboutthe board itself and help you switch overfrom an old Pi, and then we show you howto turn it into either a home theatre PC or useit as a full-blown desktop PC – it really is thatpowerful! And do you remember the robotthat we built together way back in issues 2and 3 ofRasPi?Well, check out the kit fromDawn Robotics that’s reviewed towards theend of this issue – it’s a pretty ideal presentfor someone this Christmas!Get inspiredDiscover the RasPicommunity’s best projectsExpert adviceGot a question?

We’ll fill you inQ There is another Raspberry Pi then? Is it anotherupdate, a brand new thing or something entirelydifferent? I’m getting a bit confused already!AThis time it’s the Raspberry Pi 2 Model B – basically abrand new Raspberry Pi.Q Basically a brand new Raspberry Pi?AWell the thing that truly counts, the thing that makes ita Raspberry Pi, is the chip that powers it. The BroadcomBCM2835 chip is literally the core of the original RaspberryPi, the system-on-a-chip that had the ARMv6 700 MHzprocessor and the VideoCore graphics chip. This was whatwas on the compute module from a while back, alongwith the 512 MB of RAM present in the Pi Model B v2 andB+. Anyway, this chip has been updated and the RAMincreased, which is what really makes it the Pi 2.Q What is the new chip about, then?AThe BCM2836 is a slightly modified version of the 2835– the main difference is that it now has an ARMv7 quad-“TheBCM2836is a slightlymodifiedversion of the2835 – themain differenceis that it nowhas an ARMv7quad-core,900-MHz chipand 512 Kb ofcache”BelowThis littleprocessor here iswhat’s boosting upthe Raspberry Pi 2
