| [* black] This neat little coil feeds the Pixel C's parasitic keyboard, when it's connected in the proper screen-covering position. | |
| [* icon_note] Having no ports of its own, the keyboard needs inductive charging from the tablet to function. We'll find a twin to this coil in the peripheral. | |
| [* black] Under the coil, we find a control board—probably responsible for turning boring old DC power from the battery into exciting, varying-magnetic-field-generating AC to power the coil. | |
| + | [* icon_note] Chips found on this PCB include a STMicroelectronics [link|https://www.st.com/content/st_com/en/products/microcontrollers-microprocessors/stm8-8-bit-mcus/stm8s-series/stm8s-value-line/stm8s003f3.html|STM8S003F3] 8-bit microcontroller, a Semtech [link|https://www.semtech.com/products/power-management/special-functions/ts32101|TS32101] DC-DC boost converter, and a Semtech [link|https://www.semtech.com/products/wireless-charging/linkcharge-ics/ts51231|TS51231] wireless power system transmitter. |
| [* black] We also get to peel out this record-breaking headphone jack port with the longest tail ever. | |
| [* black] It actually does double duty as an interconnect cable for the inductive coil and the right speaker. |
