The Official RaspberryPi Thread

Just placed an order with Electrocomp Express (Farnell's local distributor) today. They say I should receive the RasPi in 3-5 weeks. I will let you know hot it goes.
 
Got my dhl mail today! To bad I won't have time to play yet.. Need to get USB hub and wifi dongle too and kb or something. Anyone using esquire mini kb and mouse?
 
Ugh. I ordered 30th of June with estimated dispatch in 12 weeks. Just got a mail saying it might be delayed by another 4 weeks. FML
 
Upcoming board revision

New revision coming out in future ;)
Update: Added locations of mounting holes. Fixed minor error in I2C paragraph. Clarified expected use of P5 connector.

Update: A lot of people are asking when revision 2.0 boards will appear in the wild. They’ll be filtering out over the next month as the last stocks of the revision 1.0 at each distributor and in each geography are exhausted. I’m aware of at least one person who has received a revision 2.0 board already (from Farnell, in the UK).

We don’t believe that the changes are large enough to make it worth “holding on” for revision 2.0, unless you have a specific requirement to add an audio codec or you need mounting holes for some industrial application.

In the six months since we launched Raspberry Pi, we’ve received a lot of feedback about the original board design. Over the next few weeks, we’ll be gradually rolling out a new revision 2.0 PCB which incorporates some of the most popular suggestions. You can determine which board revision you have by typing cat /proc/cpuinfo at the command line and looking up the hardware revision code in the following table:
Model and revision Code(s)
Model B Revision 1.0 2
Model B Revision 1.0 + ECN0001 (no fuses, D14 removed) 3
Model B Revision 2.0 4, 5, 6

There has been a small change to the GPIO pin out of revision 2.0, to add ARM JTAG support and to present a different I2C peripheral from that which is (heavily) used on the camera interface. Users wishing to produce portable GPIO code should either avoid using the these pins, or add code to check the board revision and behave appropriately.

Reset

A reset circuit has been implemented, although in the standard build the required header is not fitted. Users wishing to use this circuit should fit an appropriate header to P6. Shorting P6 pin 1 to P6 pin 2 will cause the BCM2835 to reset.

USB Output Power

The resetable fuses protecting the USB outputs have been removed. This feature was implemented on some later revision 1.0 PCBs by replacing the fuses with links; revision 2.0 permanently implements this modification. It is now possible to reliably power the RPI from a USB hub that back feeds power, but it is important that the chosen hub cannot supply more than 2.5A under fault conditions.

+5V0 Leakage from HDMI

Some users have found that connecting an unpowered Raspberry Pi to an HDMI television interferes with the correct operation of CEC for other connected devices. This was fixed on some later revision 1.0 PCBs by removing the ESD protection diode D14; revision 2.0 fixes this issue by connecting the top side of the diode to +5V0_HDMI.

SMSC +1V8

The SMSC 1V8 power has been disconnected from the system supply.

Mounting Holes!

Two 2.5mm (drilled 2.9mm for M2.5 screw) non plated mounting holes have been provided to assist with ATE test mounting. Positions of these holes relative to the bottom left of the PCB (Power Input Corner) are:

Corner: 0.0mm,0.0mm
First Mount: 25.5mm,18.0mm
Second Mount: 80.1mm, 43.6mm

Warning: If used to permanently mount the PCB – do not over tighten screws or drill out to fit larger screws, as this will lead to damage to the PCB.

LED Marking

Two minor changes have been made to the silk screen:

Just got SAB and Sickbeard running saving the files to a external NAS. Works like a dream!

Any one been able to source a USB mains power plug like this for cheap?

Update: Scap that - found it on ebay for $2 - free shipping :)

I doubt the mA output is good.
