Work done
  • Grouped the ESP32-WROOM-32E pins from the official datasheet into one primary function group per pin: Power/3V3, individual GND groups, Control/Boot, Analog/Touch, Clock/Crystal, GPIO, and Reserved/No Connect.
  • Updated terminal properties with Section, Pin Group, Pin Orientation, Sub-symbol Designator Suffix, and concise Pin Description; corrected GND pins to Ground type.
  • Removed duplicate exposed-pad schematic terminals so P_GND/39 is represented once.
  • Full grouping and validation details are documented in ESP32-WROOM-32E Pin Grouping.
Success criteria review
  • ✅ All datasheet pins 1–38 plus P_GND/39 are covered once.
  • ✅ Power, 3V3, individual GND, GPIO, control/boot, analog/touch, clock/crystal, and reserved pins are distinctly categorized.
  • ✅ Project terminal metadata now reflects the grouping with no duplicate pin assignments.
Next steps
  • If you want, I can next clean up the remaining visible duplicate-style labels for GND/NC terminals or proceed to footprint/EPAD mapping cleanup.
