Sorry if this is a dumb question but I am trying to find the schematics for the Pi 2?

Are they available?

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.

Can someone confirm which version Pi they are trying to fix.

There are mixture of names and versions.
Does it have a 26 pin GPIO with two USB or the later version with 40 pins and 4 USB ports. (as per the images above).

Thanks
Mark

Not sure if these will help

The USB_LIMIT_1A2 is driven from the LAN9514 chip Pin 35.
