Schematics for Pi 2

I'm sorry but none of this makes sense.

1) The only interface you can "commercialize" on the Pi (GPIO) is documented. So anybody can, and many already have "commercialized" it. There are

     several Pi "look a likes" that use different SoCs but include a Pi compatible (or nearly compatible in the case of the ODROID C1 and C2) GPIO header.

     And ALL of them that I know of publish their schematics.

2) The internal interfaces of the Broadcom SoC (for I2C, SPI, Serial, DMA, interrupts etc.) and the registers they use are fully documented so anybody can

     write software that uses them. I think the USB interface which is not Broadcom IP is the only exception to this.

3) Even the GPU in the SoC is fully documented which is something that no other ARM SoC has done. This allows the GPU's processing power to be

     used for purposes (innovative or otherwise) other than graphics. Because of it's complexity it is also a part of the SoC that you could never (OK

     within your lifetime even with help) fully hack.

The only thing that is not documented on the B+, 2, and 3 is the schematic ! With the main component of the Pi so well documented it makes no sense

to not publish the schematics and they have never published anything that even vaguely approaches a reasonable explanation for this. About the only

thing left is that this is to prevent a company from directly cloning a Pi using the same Broadcom SoCs. ODROID tried to do this but when push came to

shove they could not get Broadcom to sell them the chips.

If you really want to understand a schematic is the one of the two most fundamental parts of that. And it is essential if you trying to determine why that

"innovative idea" (hardware, software, or both) is not working. It also helps to greatly reduce the number of boards sacrificed in the "innovative" process.

The Raspberry Pi Foundation (AKA Broadcom ?) made an incredibly stupid decision with no advantages to them and a great disadvantage to anybody

that "really wants to to understand" the Raspberry Pi in all its variations. This is underscored by the fact that they have never make any attempt to justify

it and refuse to even talk about 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,
