Here's a look at what they found!
● Dual-core, 64-bit Apple A8 chip
● Ethernet, 802.11a/b/g/n/ac Wi-Fi, IR receiver, and HDMI 1.4 connectivity
● The optical audio out has gone MIA.
● The micro-USB port has morphed into a USB-C port
● The redesigned power supply is rated at 12V at 0.917A. Compare that to the 3rd-gen Apple TV's main reactor, which pumped out 3.4V at 1.75A.
● Siri Remote features ST Microelectronics STM32L 151QD ultra-low-power ARM Cortex-M3 MCU and Broadcom BCM5976C1KUB6G touch screen controller (as seen in the iPhone 5s/5c and iPad Air)
● Siri Remote battery is soldered to the Lightning port.
Apple TV (4th Generation) Repairability: 8 out of 10 (10 is easiest to repair).
● Modular construction and only a few major components simplifies repair.
● The power supply is a separate, replaceable component, and even its AC-in jack is modular.
● Standard Torx screws used throughout, nothing proprietary.
● The remote is held together with adhesive, but a wide gap makes it easy to pry apart.
● The remote's battery and Lightning cable are soldered together—but not to anything else, so they should be an inexpensive component to replace.
● Everything important is soldered to the logic board, meaning replacement or board-level soldering is required to solve port problems.
