The Raspberry Pi single-board computer has been around for a little over two years in its original Model A and Model B versions, and in that time, it’s become a very popular platform for electronics experimentation. With many of the same capabilities as a regular desktop or laptop PC, but at a small fraction of the size and cost, the Raspberry Pi offers features like network connectivity and significant processing power for robots and other electronics projects.
We’re now selling the new Raspberry Pi Model B+, which improves on the Model B in a number of ways:
- More GPIO pins are available on a 40-pin header; the Model B has a 26-pin GPIO header.
- The number of USB host ports has been doubled to four.
- Switching regulators lower the power consumption of the Model B+ by 0.5 W to 1 W compared to the Model B (which uses linear regulators), while audio is improved by a dedicated low-noise power supply.
- A much smaller microSD card socket replaces the previous full-size SD card socket.
- Audio and composite video output are combined on the 3.5 mm jack, and many of the connectors extend much less past the edge of the board (as does the inserted microSD card).
- Four mounting holes provide more flexibility in mounting the Model B+.
We’ve seen our customers build lots of cool projects with the Raspberry Pi, including a wirelessly-controlled Zumo robot with a video camera and a robotic ping-pong ball collector. We look forward to seeing what you’ll do with the Model B+!
