Raspberry Pi Part 3

Oh how soon I forget.


Anyway I am still working on my projects using Raspberry PI and I have expanded my collection of micro computers.

My stead fast Raspberry PI Model B w/512 memory (I actually have several of these.)

A BeagleBone Black (not sure what I am going to use this for yet but stay tuned.)

An Arduino Yún, now I really don't know what I am going to do with this one but it could get dangerous,

Now recently I have obtained a Raspberry PI Model B+.

The B+ is still a device using the ARM processor, has 512M of ram and the same footprint after that it starts with some obvious mods to the architecture.

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.

More USB.  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.  It also is a little bit of a fight to get the card out.

Raspberry Pi B+ mechanical specs
Mechanical specs: you’ll want to look at these if you’re building cases or other housing.

So what do you think ??  Is this new and improved version (all of their marketing announcements) going to give us more bang for the buck ??

Well it draws less power (great for running on just batteries), your audio comes out of the old composite plug (this plug provides both audio and video), and the GPIO has been messed with.  The articles in LINUX and Raspberry Pi Geek say a few (??) of the daughterboards/shields that worked on the non-plus model will work on the plus model but they didn't give a list of those boards.  Both magazines indicated that the other vendors and RS are already producing new boards to replace the non-functioning boards.

Is this a winner ?  well time will tell.  Meanwhile jump in a try one of Model B's out

Later for now
