Human touch needs to be processed by a brain. Touch Bar needs to be processed by a chip. With some surgery we find the Touch Bar brain:
Broadcom BCM5976TC1KUB60G touch controller
Removing the OLED strip is difficult enough, but our efforts will not be in vain! Maybe a little in vain. Okay, our efforts were crushed (along with our hopes and dreams). The Touch Bar is fragile.
To add to the fragile mystery that is the Touch Bar, we stumble across an unmarked chip. Given the location, it is likely a display driver of sorts.
After scraping out all that business we uncover a three-microphone array. What is the leftmost one even listening to? The fan? The keyboard? Who knows!
