Raspberry pi B-Plus

The Raspberry Pi Model B+

OMG OMG OMG, did you hear? There's a Raspberry Pi called the Model B+ and check it out...more USB ports, more GPIO, better power supply, four mounting holes, less sticky-out SD card! Yep, that's right, the fantastic engineers at Raspberry Pi HQ have blessed us with a new design. They've taken all the feedback over the last 3 years and rolled out a nice updated Pi with many fixes and extras...all at the same price! Take a deep breath and buckle up, because Adafruit has this freshness and we're going to break it down for you. We have a big tutorial that we're keeping updated, with all the nitty-gritty details, so check that out when you have a moment

Here's a brief overview of what's new
    Dual step-down (buck) power supply for 3.3V and 1.8V
    5V supply has polarity protection, 2A fuse and hot-swap protection (so you can plug/unplug USB without resetting the board)
    New USB/Ethernet controller chip
    4 USB ports instead of 2 ports
    40 GPIO pins instead of 26. The top/first 26 pins match the original layout, 9 additional GPIO and 2 EEPROM Plate identification pins
    Composite (NTSC/PAL) video now integrated into 4-pole 3.5mm 'headphone' jack
    MicroSD card socket instead of full size SD
    Four mounting holes in rectangular layout
    Many connectors moved around

What's not new:
    Same basic size, 85mm x 56mm
    Same Processor, Broadcom SoC running at 700MHz (can be overclocked)
    Same RAM, 512MB soldered on top of the Broadcom chip
    Same power connector, microUSB
    Same software - be sure to run the latest Raspbian/NooBs but otherwise the overall Linux software is the same
    First 26-pins of GPIO are the same
    Same HDMI port
    Audio part of the A/V jack is the same
    Same Camera and DSI Display connector
