Those of you who have been following this site know that we are a big fan of Raspberry Pi products. Two years since the launch of Raspberry Pi Model B, the Raspberry Pi Model B+ has been launched. As the creators put it, this the the final evolution of the original Raspberry Pi. The Model B+ uses the BCM2835 application processor and has 512 MB RAM. Here are the improvements according to the team:
- More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
- More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
- Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
- Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
- Better audio. The audio circuit incorporates a dedicated low-noise power supply.
- Neater form factor. 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.
The Raspberry Pi Model B+ is still very affordable and a wonderful gift for DIYers. It is shipping now.
