  • 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)

  • KICM224AY4402TWNA12029, 64 GB of Kioxia NAND flash memory.

  • Qualcomm SDR865 5G and LTE transceiver

  • Qualcomm SDX55M 5G modem-RF system and SMR526 intermediate frequency IC

  • USI/Apple U1 ultra-wideband chip

  • Avago AFEM-8200 high/mid power amplifier with integrated duplexer

  • Apple APL1094 343S00437 power management IC

Un po' di calore (anzi molto calore) e una certa azione di leva ci fa estrarre due schede al prezzo di una! Dividiamo in due la scheda di uno degli iPhone 12 per rimirare tutto quel bel silicio; se vi sembra difficile capire quale dei due, non siete i soli: le schede logiche del 12 e del 12 Pro sono quasi identiche, salvo alcuni numeri di serie.
