Introducing Raspberry Pi model B+, credit-card sized little computer upgraded with additional 2 USB without performance loss for same price
Published: Mon, 14 Jul 2014 by Rad
In the two years since we launched the current Raspberry Pi Model B, weâ€™ve often talked about our intention to do one more hardware revision to incorporate the numerous small improvements people have been asking for.This isnâ€™t a â€œRaspberry Pi 2â€³, but rather the final evolution of the original Raspberry Pi. Today, Iâ€™m very pleased to be able to announce the immediate availability, at $35 â€“ itâ€™s still the same price, of what weâ€™re calling the Raspberry Pi Model B+.
The Model B+ uses the same BCM2835 application processor as the Model B. It runs the same software, and still has 512MB RAM; but James and the team have made the following key improvements:raspberrypi.org
- 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 weâ€™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. Weâ€™ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
