The original GPIO connector had five pins labelled “do not connect” to provide for possible future additional I/O connections. Now that the 4 new I/O nets actually go to a separate connector, does that mean we can rely on the “DNC” pins on P1 being connected to ground?

Yes (note – 5V and 3V3 for some of the pins).
The ground and power rails are useful to have available at the P1 GPIO, so I'm happy we have official permission to rely on them nowJBeale on September 5, 2012 at 5:36 pm said:
So to be specific, I gather we may now rely on these P1 GPIO pins to remain as shown in the Rev1 schematic.We should update the elinux wiki to that effect.
Code: Select all
P1-04: +5V0 P1-09: GND P1-14: GND P1-17: +3V3 P1-20: GND P1-25: GND

I think so. I'll put another release of RPi.GPIO out shortly that will let you specify board revision to compensate.c.cam108 wrote:Are the changes to the GPIO allocation connector going to break the pin naming used by GPIO libraries?

The only question I have now is how are thieves going to steal my future boards if I can route the barbed wire through the handy-dandy mounting holes instead of the RCA jack?
Someone posted a picture in advance of the announcement - think the thread was locked and/or since-zapped so as not to preempt news release. Picture URL is [Mod removed - please don't repost] - credit to the original poster whose identity I cannot find.arm2 wrote:Re P5 and CASES
"... suitable attachment point for third-party clock and audio codec boards, and is pinned to be mounted (ideally) on the underside due to connector clash"
Errr I don't think I've seen a single case that could cope with any board mounted underneath!
Unless P5 is between two connectors why can't it be mounted on top going away from the clshing connector?
Photo's soon please! A good job our next design of RTC ran late, otherwise I'd have ordered them last week.
