DIY and gadget fans alike love the Raspberry Pi. Now, they'll have more to love with the new Raspberry Pi B+ .

For the same $35 price as the original Model B , the Model B+ still uses the ARM-based Broadcom BCM2835 chipset, 512MB of RAM, and 700MHz low-power ARM1176JZ-F applications processor.

The improvements come with a more space efficient microSD card slot in place of the SDCard slot. It also has four USB 2.0 ports instead of the Model B's two. The new single-board computer (SBC) also has 40 general purpose Input/Output (GPIO) pins. The Model B has only 26. The B+ also has a single four-pin port for both both audio and video output. The audio circuit should also deliver cleaner sound with a new low-noise power supply.

Last, but not least, the B+ uses a half to full watt less power. If you're been working on Raspberry Pi projects that require long battery life, this is the SBC you've been waiting for.
