ESP32 Part Audit

Worked for 46 sec

flux

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

Thought for 46 sec

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.

Thought for 24 sec

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.

Worked for 3 mins 2 sec

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.
