Schematics for 12.9 Pro 2nd gen

Sadly, not all of the schematics and board views have fallen off the back of Apple’s truck ;-{

Apple is trying hard to prevent these from leaking out.

There are two sides to this argument!

Apples position is allowing competitors access to how they do things given them a head start. The other is allowing people to fix their own systems.

While I can see their points I’m sure the competitors have smart people who have taken the time to tear down the device and reverse engineer the design. As many of the components are off the shelf it wouldn’t take much to figure things out and even if the chip is custom its not hard to create a blackbox on what’s happening inside. Digital signaling is on the most part is straight forward (Zero’s and One’s)

Keeping people out also doesn’t stop people with the skills from repairing systems it only slows them down, and in many a case issues of bad design where often caught by the independents. iFixit has collectively ID’ed many failures Apples and others! So we are often the watchdogs keeping the makers honest (as best as we can).

It’s taken time, we are making headway! Give it a bit more time things are moving! Hopefully we will have all of the needed info to do repairs.
