Schematics for Pi 2

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.

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%?

Parker, i have it too, but too many information misssing. What about points 41 trhu 57 , my problems is on usb ports .

As Shabaz and Gary have said, with only a partial schematic, these points have not been disclosed. I have not been able to find any suggestions on any other forums either, unfortunately. Can you explain more clearly what the problem  you are experiencing is? Maybe we can find more useful information from there that can lead to a solution rather than use the test points?

EDIT: Also you could have a look at RPi's USB Documentation

Parker, i don´t think is this the right place for the problem , but..

My problem is similar as this https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=110164&p=760997

Make the sugestions with no result.

If anyone has any other information to complement, I'll updating the image.
