Massive guide to new Raspberry Pi B+

There's a new Raspberry Pi model out, the B+, and the nice folks at Adafruit have delivered a massive guide to working with the technology (just in time!).

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

* 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
