Sleep om te herschikken

Finally, we get to the core of all things: the Apple-designed S4 system-in-package.

Good news, everyone! The S4 is secured only with screws, and pops right out—a welcome change from the fiercely-glued SiPs of years past.

As always, the package itself is encased in a solid block of resin, meaning most of its secrets will be difficult to extract. Thankfully though, the RF components remain a little more exposed:

Avago AFEM-8087 (likely front-end module)

OU JQ

YY MEH ECE (this looks like a Bosch part, likely the fancy new accel + gyro)

AE827 I2033 0836

ST Microelectronics ST33G1M2 32-bit MCU with ARM SecurCore SC300—the same eSIM we found in the last Apple Watch and in the iPhone XS and iPhone XS Max.
