Raspberry Pi Model B+

At some point in the future, there will be a brand new version of the Raspberry Pi, likely dubbed Raspberry Pi 2. For now, however, the Raspberry Pi Foundation decided to tweak the original model one final time by implementing several requested upgrades, and what emerged is the Model B+. It uses the same BCM2835 application processor as the Model B and still has 512MB of RAM. Heck, it even costs the same (or at least it’s supposed to) — $35. So, what’s new?

There are now four USB 2.0 ports compared to two in the Model B, and they feature better hotplug and overcurrent behavior. You’ll also find that the GPIO header has grown from 26 pins to 40 pins, lower power consumption thanks to replacing linear regulators with switching ones, improved audio with a dedicated low-noise power supply, and a push-push microSD card slot to replace the old friction-fit one.

All of this comes wrapped in a neater form factor — the Raspberry Pi team aligned the USB connectors on the Model B+ with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
