ESP32 Part Audit

flux

The keepout boundary and edge-placement rule are added. I’m doing a final geometry/read-back check now.

flux

Added and verified the official antenna guidance:
  • 18 × 7 mm antenna keepout at the antenna end
  • Enforced exclusion for copper, routing, vias, and components
  • Dashed boundary and ANTENNA KEEPOUT label
  • Edge-placement rule with the antenna end facing the carrier-board edge
The footprint now reflects Espressif’s preferred placement. The separate 15 mm enclosure/metal clearance remains system-level guidance rather than footprint courtyard geometry.

Organize the terminals into proper pin groups, sections, orientations, and terminal order.

flux

I’ll organize the single parametric symbol by function—power/ground, analog inputs, GPIO/peripherals, UART, reserved PSRAM, and NC—then verify that all pin numbers and footprint mappings remain unchanged.

flux

Organized and verified all 47 terminals:
  • Functional sections for power, ground, control, GPIO, communication, analog, reserved PSRAM, and NC
  • Deterministic pin groups and terminal ordering
  • 3V3 on top; grounds, EPAD segments, and NC pins on bottom
  • Inputs on the left and outputs on the right
  • UART RX/TX separated for correct opposing orientations
  • IO16 isolated as embedded-PSRAM/reserved
All existing pin numbers and footprint mappings were preserved.
