We put on our best chip detector specs and go to work. Here's what we can identify so far:

Apple APL1W85 A13 Bionic SoC layered over SK Hynix H9HKNNNCRMMVDR-NEH LPDDR4X (seemingly 4 GB, but SK Hynix needs to update their decoder)

Apple APL1092 343S00355 PMIC

Cirrus Logic 338S00509 audio codec

Unmarked USI module—teardown update: it turns out that this is where Apple's new U1 ultra-wideband chip is hiding. Read all about it in our blog post.
