  • 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.

La rimozione della schermatura della scheda ci mostra gli artisti che danno vita allo spettacolo di luci sovrastante:

Driver LED Texas Instruments TLC 5971

System-on-Chip programmabile Cypress CY8C4245LQI-483

Il lato inverso della scheda ospita i LED e il diffusore che dà all'indicatore il suo look nebuloso.

I simboli più e meno sono ritagliati direttamente nella scheda e ognuno ha la sua piccola triade di LED e una guida luci per dirigere i fotoni dove ce n'è più bisogno.

La parte superiore della scheda (seconda foto) mostra uno schieramento ben organizzato di piccole sporgenze: probabilmente una griglia capacitiva,come nel Google Home, per registrare i tap e i tocchi con le dita sulla superficie soprastante.
