Does anyone know what the revision ID of the new model A+ is as reported by /proc/cpuinfo ?

I hope it's the same as the B+.

Is the GPIO pin out the same as the B+ ? I expect that it almost certainly is but experience has taught me to never assume anything!

Yes the pinout is exactly the same

Why has it not got a OptaCore CPU, trillion megs of ram and can run for a week of a battery, damn all the want dreams have evaporated ;)

You forgot the wheels and sandwich.

Seriously, I was a bit surprised by the new price. That'll have a lot of other makers thinking hard...

That wouldn't be logical. You need to be able to determine the hardware capabilities from a simple software check.

I don't. I'm only interested in which goios are present.

No changes are required to the pigpio software to work with the A+.

Farnell appear to be showing an image of the Version 1.0 A+ board "for illustrative purposes only" which seems slightly different to the Version 1.1 board detailed in the official announcement. Most notably the positioning of the USB socket, and visibly in the colour of the camera and display connectors.

The leaked-early images of the A+ also seem to be version 1.0 boards.

Version 1.0 -

Version 1.1 -

Will all boards on sale to the public will be version 1.1 boards ?

You are one thousand percent correct.

This is why leaked images are bad, m'kay.

The version pictured on the Raspberry Pi blog page is the version that you will receive.

From Eben's interview at linuxvoice.com:
Eben says it’s ‘electrically identical’ to the Model B+. This means the A+ now benefits from the B+’s improved power chain, meaning you don’t need the mother of all micro USB power adaptors to keep your Pi running or a powered USB hub to enable the use of USB storage.
Does that mean, that it has the same USB current values incl. the high power 1.2 A mode? And the same polyfuse tripping value?
Minimal Kiosk Browser (kweb)
Slim, fast webkit browser with support for audio+video+playlists+youtube+pdf+download
Optional fullscreen kiosk mode and command interface for embedded applications
Includes omxplayerGUI, an X front end for omxplayer

There is no USB current switch on the A+ but the polyfuse is the same as a B+ with 2.0A rated current - allowing the use of high-powered peripherals.

Can the A+ be back-powered using main USB?

Am I right in thinking that the USB port was moved to increase the chance than an A+ would be usable in a B+ case?

I just bought 2 of these at MCM Electronics. I then headed over to the RPI documentation page and there is nothing there for the A+. Where can i get information on this as far as, layout drawings for hole placements, I/O connector pinouts and so on ?

AFAIAA apart from the USB Port it is identical to a B+ with the end of the PCB cut off

Weight: 23g

Price: cheaper even than model A !

Power consumption: "lessthan Model A" - but how much ?
Android app - Raspi Card Imager - download and image SD cards - No PC required !
