  • Much like the Function Keys model, the trackpad in the Touch Bar unit slides out easily after dispatching ten T5 Torx screws.

  • We can also happily report that the trackpads from these respective models are identical, and likely cross-compatible.

  • The cable routing, however, is different to accomodate the modified logic board design. So, if you're planning on replacing a busted trackpad, be sure to hold on to the original flex.

  • In case you missed it, here are the ICs we identified the first time around:

  • STMicroelectronics STM32F103VB ARM Cortex-M3 MCU

  • Broadcom BCM5976C1KUFBG Touch Controller

  • Maxim Integrated MAX11291ENX 24-Bit, 6-Channel Delta-Sigma ADC

  • Monolithic Power Systems MP24830 white LED driver

与功能键版本非常类似，Touch Bar版本的触控板单元在拧下十颗T5 Torx螺丝后很容易滑出。

我们还可以高兴地讲，这些来自不同型号的触控板是相同的，并且可能是交叉兼容的。

然而，电缆布线不同于适应经过修改的逻辑主板设计。所以，如果你打算替换一个破损的触控板，一定要使用原来的柔性印刷电路。

以防你错过了，这里是我们最初确认的一些IC：
