			== Models ==
			Most will purchase the model B, which has Ethernet and more USB ports

			The second release of model B has 512 MB RAM in lieu 256 MB
			*likely to increase the variety of OS that are usable
			*earlier boards are not upgradeable, because all components are soldered in place

			== Case ==
			The basic product is sold without a case. It does not fit in any "standard" blank case and has sockets on both sides as well as all four edges, making construction of a suitable case not a simple task.

			Cases are now being sold on the Raspberry Pi site. Alternatively, third-party cases are also marketed

Rpeters: added info re fragile capacitor & power supplies

added info re fragile capacitor & power supplies

New page

A growing body of information is available at http://www.raspberrypi.org

Only a couple of '''critical''' issues, that are easily overlooked, are summarised below
== Circuit Board ==
Power is supplied via the micro-USB connector at one end. The surface-mounted capacitor behind that connector is a known physical weak-point.
*do not grip the board by that capacitor
*preferably leave the micro-USB power cable permanently plugged in and power ON?OFF by either
**powering the plug-pack/USB-hub ON?OFF or
**disconnecting the other end of the power cable

== Power Supply ==
#A raspberry pi draws 0.7A (700 mA) of '''regulated''' 5V power, which is beyond the capacity of most:
#*USB sockets on a computer
#*mains-USB plug packs
#Suitable power supplies include
#*mains-USB plug packs rated at 1A
#**preferably having a '''single''' USB socket only
#*USB-hubs capable to delivering 1 A to a '''single''' USB socket
#**"Zipp" brand from Big W does - but check before purchasing
#although the use of a USB-hub as a power source is deprecated by the manufacturers, it has been used sucessfully by the developers at http://www.ipfire.org. Critical factors are:
#*regulated power to the hub
#*1 A available to a single socket
