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
OMGOMGOMG ITS A NEW RASPBERRY PI! [Adafruit]
