Following our intuition, we try for the trackpad next, and are pleasantly surprised at the ease of its removal.

This represents a huge improvement over the previous 13" MacBook Pro, where the trackpad was trapped under the battery.

We find some familiar digital hardware piggybacking on the trackpad:

STMicroelectronics STM32F103VB ARM Cortex-M3 MCU

Broadcom BCM5976C1KUFBG Touch Controller

Bosch Sensortec BMA282 accelerometer

Texas Instruments TMP421 remote/local temperature sensor

We also find the Taptic Engine, AKA the magic electromagnet behind Force Touch, to be simply secured with screws and spring contacts.
