Over 2.5 million Pis have been sold since it was released, according to TechCrunch, and a new and more powerful model called the Raspberry Pi B+ will be the final upgrade of the original Pi product line. It's available now.
Even though it's inexpensive, the Raspberry Pi is a full-fledged computer running Linux. It's hugely popular in the hacker/maker crowd, and people have used the computer to power some really cool devices.
The B+ model will still cost just $35 and features a host of improvements to make the device more modular for DIY enthusiasts.
There's two additional USB ports, a streamlined form factor, better audio performance and power consumption, and the SD card slot has been swapped for a more recent Micro SD slot.
You can check out all of the details over at the official Raspberry Pi website, or watch the video introducing the B+ below.
