Part Datasheet Audit Scope
Audit of ESP32-H2-MINI-1-H4S part metadata, schematic symbol, PCB footprint, and terminal descriptions against the official Espressif datasheet.
Key specifications Metadata review Schematic symbol review Correct items
  • Pin numbers 1–53 and their displayed names align with the datasheet pin table.
  • GPIO, EN, 3V3, VBAT, UART, NC, and GND naming is consistent for the actual datasheet pins.
Mismatches
  1. Eight nonexistent electrical pins were added: pins 54–61, all named GND. The datasheet ends at pin 53.
Audit complete. The official Espressif datasheet was already correctly linked, so no property update was necessary. The critical mismatch is 61 library terminals versus 53 datasheet pins—center GND land segments 54–61 should share pad number 49; pin types/descriptions are also missing, and the Logic/AND classification is incorrect.
Full results: Part Datasheet Audit. I also filed an internal part-quality report for correction.
Organize the terminals into proper pin groups, sections, orientations, and terminal order.
I’ll reorganize the symbol by function—power, control, GPIO/peripherals, UART/USB, NC, and ground—then verify every terminal’s section, group, orientation, and order.
Organized all 61 terminals into functional Power, Control, GPIO, Clock, Communication, No Connect, and Ground sections, with appropriate pin groups, orientations, and deterministic ordering.
  • Power pins: top
  • Ground pins: bottom
  • GPIO/control: left
  • USB/UART and NC: right
The previously identified extra ground terminals 54–61 remain unchanged pending footprint/pin-count correction.
