Raspberry Pi Cooks Up Improved Model B+ With Tasty Upgrades, Still $35
Although the B+ has the same ARM-based BCM2835 processor, 512MB RAM, and $35 price tag as the Model B, there are several key improvements, including two additional USB 2.0 ports (for a total of 4 four), a slicker push-push microSD slot that replaces the old friction-fit slot, and a 40-pin GPIO header that replaces the old 26-pin setup.

There’s also a dedicated low-noise power supply that results in better audio performance, they’ve reduced the power consumption down to between 0.5W and 1W, and they’ve adjusted the form factor somewhat. “We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes,” reads a post announcing the board.
You can buy the Model B+ starting today, but the Model B will continue to be sold as long as there’s demand.
Adafruit did a deep dive on all the new changes if you want a comprehensive overview, and we’ve had our own fun with the older Model B.
