Moving on, we direct our attention to the trackpad.

Unlike the newer MacBooks Pro, which have first-step replaceable trackpads, this trackpad shares a cable with the keyboard, which is pinned under the logic board.

As the trackpad comes out, we can't help but think of a certain TIE fighter...

The trackpad contains a Broadcom BCM5976C1 touch controller, a STMicroelectronics STM32F103B6 32-bit ARM Cortex-M3 microcontroller, a Macronix MX25L2006EZUI-12G 2 Mb serial flash memory, a Monolithic Power Systems MP6519 H-bridge current regulator, and a Maxim Integrated MAX11390A 10-bit analog to digital converter (likely).

A Texas Instruments TMP421 remote/local temperature sensor and a Bosch Sensortec BMA282 accelerometer are the only two sensors found on the frontside of the PCB.
