Schematics for Pi 2

Hi, Rod

I´m looking for too, can´t you find it?

Hi, Rod

I´m looking for too, can´t you find it?

If you read through even a few of the previous posts (generally a good thing to do before re-asking a question that has already been answered) you

would know that only limited schematics of the B+ and no schematics for the 2B or 3B have been released. Look all you want to, you won't find them

or even a hint of a official reason as to why you won't find them.

Hello Garry, thanks for your answer, but I had already seen the previous posts, a lot of them, but they are a bit old. I know it is not company policy to give access to this kind of material, but Apple also has this type of conduct and I have a lot of computers schemesof his products. It´s an absurd I have a card faulty and can´t fix it ,because it does not have access to what is basic to make a decent repair form, we can not even know officially what voltage have to have the PP27. Thanks

Actually there is a released schematic for the 3B along with the 1A/B and B+, however, there is still no schematic for the 2B.You can look here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/schematics/README.md for any released schematics.

Hi Parker,

That is a partial schematic (as mentioned by many people on this thread).

I see now that it is partial, but saw no mention of that in this thread before, but thank you for pointing it out. However, I still believe a partial schematic is still more valuable than no schematic.

A partial schematic has some value of course.

However it is of zero use to help understand the voltage at PP27, as Ricardo is asking. For that he would require a (more) complete schematic.

Thanks , for your help, guys

That´s what i´m talk about,

I see your point and agree. Also I do believe there is some information, albeit unofficial, on PP27. From here it seems to be that PP27 is the VBUS (USB 5v Power) in which case should the voltage not be between 4.75v and 5.25v as the RPi's voltage range is  5.0V±5%?

Hi Ricardo,

Sorry for the testy reply but this is a long running sore spot with me as you can probably tell by my previous responses. AFAIK it is now and for the future the (stupid)

policy of the Raspberry Pi Foundation not to release schematics (full or otherwise) for the previously mentioned Pis or even to provide a reason as to why they won't.

I keep hoping that eventually enough pressure will be applied to change it but so far I have little hope this will actually happen because there doesn't appear to be

any real incentive (read competition) to do so. It has definitely cut down but not eliminated my incentive to buy Raspberry Pis.

@ Parker

Only if the "partial" part is where the problem is, otherwise you're SOL. This is especially true with the 5+ layer boards common today as there is no way to follow

traces in the inner layers. At that point it is use a multi-meter and a LOT of probing and guessing which is also problematic due to Ball Grid Array packaging (all

the leads are under the package and therefor invisible) and very, very (very) small leads on surface mount chips.
