De-shielding that board shows us some of the fun that's running the light show up top: Texas Instruments TLC5971 LED driver Cypress CY8C4245LQI-483 Programmable System-on-Chip, likely tasked with touch control
  • De-shielding that board shows us some of the fun that's running the light show up top:

  • Texas Instruments TLC5971 LED driver

  • Cypress CY8C4245LQI-483 Programmable System-on-Chip, likely tasked with touch control

  • ON Semiconductor FPF1039 slew-rate-controlled load switch

  • Texas Instruments TPS62135 4 A step-down converter

  • The flip side of the board houses the LEDs and the diffuser that gives the indicator its cloudy look.

  • The plus and minus symbols are cut straight through the board, and each has its own little triad of LEDs plus a light guide to aim the photons where they're needed most.

  • The top side of the board (second photo) sports a neatly organized pattern of tiny divots—possibly a capacitive grid, like on the Google Home, for registering your taps and touches on the surface above.

暴露出来的电路板向我们展示了一些运行顶部提示灯光的乐趣:

电路板的顶部是LED指示灯的LED灯珠以及使指示灯呈现模糊的外观的柔光镜。

加号和减号完全由中心阵列通过安装在板上的凹槽中的导板点亮。
