What's the same?
The model B+ has many of the same features as the model B, like the processor and 512MB of RAM. It's also credit card sized, with the addition of rounded edges, and the ports sit flush against the edge instead of sticking out slightly. The operating system Raspbian is also still in use with this model and you can use NOOBS to install the latest version onto a Micro SD card.
What's different?
Lots of exciting new features on the Model B+ such as:

- More General Purpose Input Output pins (GPIO). 40 in total, with the first 26 remaining the same as the model B.
- Micro SD card slot instead of the larger SD card size.
- Improved audio for speakers and headphones
- Improved power consumption.
