Étape 12
A little heat (a lot of heat) and a little prying yields two boards for the price of one! We split one of the iPhone 12 boards open to get a look at all that sweet silicon, and if it seems hard to guess which one, you're not alone—the logic boards of the 12 and 12 Pro are nearly identical, apart from a few serial numbers. Apple APL1W01 A14 Bionic SoC, layered under Micron D9XMR MT53D512M64D4UA-046 XT:F 4 GB LPDDR4 SDRAM (6 GB RAM on the 12 Pro)

On chauffe un peu (beaucoup), on fait un peu levier et voici deux cartes mères pour le prix d'une ! Nous ouvrons l'une d'entre elles pour admirer tout son splendide silicium. Si vous avez du mal à l'identifier, vous n'êtes pas seul. Les cartes mères de l'iPhone 12 et de l'iPhone 12 Pro sont presque identiques, à part quelques numéros de série.
