Damn it I hate having Old Tech!

Please tell me that GPIO development on Rev1 will not stagnate and die.... I use the Pi for alot of GPIO stuff and don't want to be a new one! GPIO library developers please CONTINUE creating stuff for the original Pi.

Thanks

The differences are really minor, so you should be absolutely fine. The code to check which rev you have is tiny, and pretty easy to write, so any GPIO libraries etc shoudl be easily able to accomodate the changes.

The only thing I can see that affects my simple GPIO Pyhton handler for Scratch is the change to Pin13 but I really don't understand what the change is/for/why but mainly can I still use it as one of the "general purpose" straight forward GPIO inputs/ouputs like the other ones e.g Pins11,12,15,16,18,22 and 7

Glad of -

1/ Mounting holes
2/ 1V8 fix for reliability across all boards made
3/ HDMI fix
4/ Fuses gone

Looking better. Says he who just modded his China version for better GPIO connector as I will be plugging various cables and boards in and out over next few weeks.

It's a shame on rev 2 the USB is not in line with the edge of the board and the sd card swapped for micro sd flush mount.

Not that I'm that bothered but it would be nice to have all the edges in line with no sticky out bits.

I bet a lot of case designers disagree with you on that!

There is no obvious way the usb could be pulled back, anyway, that would require a massive redesign. The ethernet could have been stuck out further to match, but that is not really any better.

As it is, a lot of case designers are going to need to think about how to deal with the mounting holes... (I need to visit local hardware stores and see what there is in the way of M2.5 fittings...or what the closet size SAE is that isn't any bigger than that is...6-32, maybe?)

so, apart from the new GPIO and the mounting holes, what do I have to do to upmod my version 1 raspi to a version 2?

Oh, and is there *anything* we can do with those 'between the RCA and the analogue audio socket' pins that might make us earlyish birds feel superior over the new folks?

But if you want your design to be compatible with both revisions then you can not rely on the mounting holes. And if you want to use them even optionally you will need to consider Rev1's D10 very carefully.

If you have access to archaic fixings, 8B.A. at 2.2mm dia will be a sloppy fit. If the fixing holes are truly 2.9mm dia, then 6B.A. (2.8mm dia) will be a nice snug fit. For the Americans, a #2-56 or #3-48 should fit the bill (#4 or larger is going to be too big).

SAE (either NF or NC) I can get...older than that, probably be hard to find (I know of one likely place, but I've never actually been there...just had it mentioned in reference). It's quite likely I can get the right metric sizes, though. The 6-32 was a guess from looking at the board pic. You are probably correct about not going over 3-48.

As for the other comment about case issues...if provision is made for a spacer sleeve on the bolt, under the board, one could ahve a case that accommodates either version. Another alternative would be a supporting plastic sleeve that comes to the bottom of the board (Rev. 2.0), but can be carved away for a Rev. 1.0 board. It would be a one directional change, though.

In time, it is likely that the market for Rev. 1.0 cases will dwindle away (so I guess the best bet is to stock up on a few extras while one can get them....)

Question as Revision 1 has proven not worthy, under UK law are we entitled to a free upgrade and return of these sub par cards to get the Version 2 cards which clearly fixes quite a few issues

if i buy a £10000 car and it was deaned not fit for purpose i would get money or replacement how does it work with the Pi.?

Yes! If you buy a car and the manufacturer adds an extra socket in the next revision you are definitely entitled to a full refund, and you can keep the original car as well.

Actually, though, there is nothing added in the Pi rev2 that could not be made available on the previous boards with some very delicate soldering. You may find it cheaper to hire than engineer than a lawyer.

No, because it is worthy and not sub-par. But if you really want to try it on, contact the people who sold it to you. Although in your case it won't make any difference as the problem you are seeing is a software one, not a hardware one.

If you bought a £10000 car and it wasn't fit for purpose and that purpose was ploughing a field, it's your fault you bought a car not a tractor.

glad it made you smile worth a try i bet even on ebay now the revision 1s wont sell for what we bought them for.

you cannot please some people any of the time.

all i wanted was the USB port to work and react the same as every other linux box on the plant but it still seams to hard to fix.

I get that you feel burned that the USB has problems, but I'm afraid we're all going to have to live with what we've got - the new revision doesn't fix all the USB problems, and the USB problems it *does* fix are doable on the Rev.1 Raspis with a bit of soldering...

What's with the whiners. It's only $35. Donate your rev 1 to a school and order a rev 2. Remember to get out of the house and enjoy life.

Only thing is that if we mod our Rev1s to be fuseless, we void our warranty I'm assuming ?
I don't particularly mind...I've voided my warranty already because the SD card broke the socket lol.

Just wait a few years and sell it as GENUINE version I Raspberry Pi Model B with 256MB of RAM. People will say, "how quaint!" and pay a premium for it. then they'll show it off next to their Rev. 6 with 16GB at 6GHz Pi.

Just FYI, the requirement for the poster is to support 2x13 port powered hubs, something I would bet some Iinux devices won't support. The problem he is seeing is, I believe entirely software related, a problem which is being worked on, but that won;t be fixed by changing to the Rev b.

First 10,000 batch Raspberry Pis with no CE Mark are going to be **SPECIAL**.

I have two Rev 1s and I have been happily playing with them without noticing that there was any problem that needed to be fixed! They seem perfectly perfect to me.

I am ordering a Rev.2 for my collection and can now retire my non-CE Pi as a keepsake.

And I've a Gertboard on order, the great thing about Gertboards is that they are Made in [Insert nation of purchaser here].
