What's the same:
- Same Broadcom BCM2835 Chipset
- Same 512MB RAM
- Same full size HDMI port
- Same 10/100 Ethernet port
- Same CSI camera port and DSI display ports
- Same micro USB power supply connection
What has changed:
- Now comes with 4 USB ports so you can now connect more devices than ever to your Raspberry Pi.
- There is a 40pin extended GPIO so you can build even bigger and better projects than ever before. The first 26 pins are identical to the Model B to provide 100% backward compatibility for your projects.
- Micro SD slot instead of the full size SD slot for storing information and loading your operating systems.
- Advanced power management:
-You can now provide up to 1.2 AMP to the 4 USB ports
– enabling you to connect more power hungry USB devices without needing an external USB hub. (This feature requires a 2Amp micro USB Power Supply)
- The B+ board now uses less power (600mA) than the Model B Board (750mA) when running
- Combined 4-pole jack for connecting your stereo audio out and composite video out

- learc83 12y agoRight now it's possible to back feed power with a powered hub instead of using the micro USB connection. I'd like to see the schematic to find out if that's still possible, but I can't find one yet.
- Already__Taken 12y agoThis isn't a good idea though I've heard, don't you bypass some important components for power safety in the micro USB power circuit?
- learc83 12y agoYou're bypassing a fuse. If you have a crappy powered hub that isn't well regulated you could fry your pi. In reality, the chance of that happening is very small, and safety here is only in the context of the "safety" of a $35 board. Most hubs won't let you draw more than a couple of amps anyway.
- Alupis 12y agoWell, I'm not sure how well regulated my $3 powered usb hub is. I find myself having to do this weird ritual of plugging stuff in under the correct sequence otherwise I get some power from the hub and the pi won't boot fully (goes into a weird boot loop).

- nodata 12y agoplus better mounting.
- kephra 12y agoI'm still missing a normal round power plug, as the ramshackly micro USB draws much more power then the allowed 500mA. Also Ethernet is still connected via USB, and horrible slow.
- durin42 12y agoThe Ethernet chip is a new one tho - maybe it's a little less terrible? (No idea - my applications for the rpi don't depend on it being a speed demon on the network.)
- jedahan 12y agothe ethernet chip seems to just be the 4 usb-port version instead of the 2 usb-port version.
- Alupis 12y agoThe Ethernet speeds are limited by both the USB bus it's riding on, as well as the slow CPU processing power. Although, for most of my projects so far, it's been plenty fast.
- tlrobinson 12y agoAny recommendations for similar small/cheap devices with better Ethernet?
- fanf2 12y agoHave a look at the Beaglebone Black.
- kephra 12y agoBut as far as I read, the PI can still not boot over Ethernet, which is a requirement for me to boot into backup cycle (Installation = Restore), and it still can not wakeup on LAN.

- Kurtz79 12y ago-You can now provide up to 1.2 AMP to the 4 USB ports enabling you to connect more power hungry USB devices without needing an external USB hub. (This feature requires a 2Amp micro USB Power Supply) Nice. In my experience, using a good power supply for the pi (instead of cheap ones selling for 5 bucks on ebay) is mandatory also in the current revision, and solves a lot of problems with video and USB devices (for example, cellular modems). The Apple iPad charger works wonders.
- yowmamasita 12y agoThe Samsung chargers as well, LG chargers unfortunately just only give 0.8A
- Paddy356 12y agoThe Pi Shop sell a high power adapter http://www.amazon.co.uk/Adaptor-Supply-Charger-Tablet-iPhone-White/dp/B00II8ZVKK/ref=sr_1_1?m=A3CVKP0CMU7W56&s=merchant-items&ie=UTF8&qid=1405816988&sr=1-1&keywords=adapter http://www.amazon.co.uk/Adaptor-Supply-Charger-Tablet-iPhone... with full 2A and dual USB ports.
- Alupis 12y agoThis is quite the impressive release. The additional USB ports are a welcome addition, as-is the additional GPIO. I have one project in particular that will benefit from the additional GPIO. The microSD slot is also a big deal. microSD's are much more common now-days than SD's due to most people's phones having them. I own a slew of old mSD's from old phones and can re-purpose them into a Pi project now :)
- JTon 12y agoAgreed. Big win on the microSD. They are also becoming very affordable, especially < 32GB
- whyenot 12y agoThe microSD card and changes to the ports (more flush USB) also reduce the footprint which means I should be able to cram a new version of my Pi motion activated camera into a smaller waterproof case. This makes me very happy. The lower power demands may also let me get away with using a smaller battery and solar panel.
- chillingeffect 12y agoCurrent != power. I recommend altering this to say "uses less power (600mA at X volts) than the old (750mA at Y volts)," filling in X and Y with the voltage that the systems run at. Or: "uses less power(X mW) than the old one (Y mW)," filling in X and Y wit hthe power that the systems run at.
- dubfan 12y agoPower = Current * Voltage so just giving the voltage doesn't help either. I believe the voltage is unchanged so stating a decrease in amperage would suffice.
- GutenYe 12y agoHave them fixed the broken USB system? (USB and Ethernet share the same bus problem)
