A new version of the Raspberry Pi — the $35 credit card-sized computer — will have a few design changes that will make it more robust, and it will still come with the same low price tag.
For those that aren't familiar, the Raspberry Pi is a low-cost, low-powered full computer that has been used by everyone from tinkerers to educators to gadget-makers.
Developed by the UK-based Raspberry Pi Foundation and first launched commercially in 2012, more than 3 million Raspberry Pi boards have been sold. For $35, users get a super-tiny computer that can run Linux and be used in a variety of situations. A whole secondary industry has cropped up around the device, with third parties creating everything from add-on modules to cases to specific appliance builds.
Now the Raspberry Pi Foundation has announced a hardware revision to the original Raspberry Pi Model B, the Raspberry Pi Model B+.
The Raspberry Pi Foundation is quick to point out that the Model B+ is not a Raspberry Pi 2, "but rather a final evolution of the original Raspberry Pi."The Raspberry Pi Foundation is quick to point out that the Model B+ is not a Raspberry Pi 2, "but rather a final evolution of the original Raspberry Pi."
The Raspberry Pi Model B+ still sells for the same $35 and has the same application processor and amount of RAM (512MB), but here are a few other changes:
- More GPIO pins — Model B+ has 40 GPIO (general purpose input/output) pins, as opposed to 26 on the original. This means users can connect the Raspberry Pi to even more sensors and expansion boards.
- More USB ports — The original Model B had 2 USBS 2.0 ports. Model B+ has 4 USB 2.0 ports.
- Lower power consumption — The Model B+ consumes 600mA of power, compared to 750mA on the original.
- Better audio — The audio circuit now has a dedicated low-noise power supply.
- MicroSD — The Model B+ has a microSD card socket with a better push socket. The original Model B used SD cards.
- Better form factor — The new Model B+ has aligned USB connectors with the edge of the board, has moved the composite AV output onto the 3.5mm jack, and there are now four mounting holes.
The Raspberry Pi Foundation says that even though it thinks the Model B+ is a better fit for most users, it also understands that lots of industrial customers have created specific setups for the Model B. As a result, it will continue making the Model B units as long as there is demand.
You can get the Raspberry Pi Model B+ from element14, Allied Components and other Raspberry Pi shops.
