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.

Looks like any trackpad repairs will have to go through logic board removal first.

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

Some Star Wars tech on this 'pad:

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.
