ESP32 LCSC Part Verification

flux

Verified the ESP32-S3-WROOM-1-N8R8 / LCSC C2913201 part project.
Findings
  • Symbol pin numbers/names 1–40 look correct against the Espressif datasheet, including:
    • pin 2 = 3V3
    • pin 3 = EN
    • pin 16 = IO46
    • pin 26 = IO45
    • pin 27 = IO0
    • pin 36 = RXD0
    • pin 37 = TXD0
    • pin 40 = GND
  • Exposed pad mapping is not fully proven. The datasheet has EPAD / pin 41 as GND. The project represents this as 41_1 through 41_9, which is reasonable for a split thermal pad array, but the indexed footprint data did not expose enough pad-number detail to confirm every footprint pad maps cleanly to the symbol terminals.
  • Key metadata is incomplete. The project has the datasheet URL and part type, but appears to be missing explicit:
    • Manufacturer: Espressif
    • MPN: ESP32-S3-WROOM-1-N8R8
    • LCSC number: C2913201
    • Description
    • Package / footprint name
    • Operating voltage: 3.0–3.6 V, typical 3.3 V
    • Required supply current: 0.5 A
    • Operating temperature for N8R8: –40 to 65 °C
  • Terminal electrical types are weak. All symbol terminals appear to have Pin Type: Unspecified / Terminal Type: unspecified. That should be fixed so ERC and downstream users understand power, ground, input, output, bidirectional GPIO, enable, and UART pins.
  • Documentation should flag ESP32-S3 variant caveats.
    • IO0, IO45, IO46, and IO3 are strapping-related.
    • RXD0 / TXD0 are also GPIO44 / GPIO43; aliases or descriptions would reduce confusion.
    • For the N8R8 PSRAM variant, IO35, IO36, and IO37 should be documented as restricted / not generally available due to internal Octal SPI PSRAM usage.
Recommended fixes
  1. Add explicit project metadata: manufacturer, MPN, LCSC PN, package, description, supply voltage/current, temp range.
  2. Set terminal types instead of leaving everything unspecified.
  3. Verify the actual footprint file pad names/numbers for pads 1–40 and EPAD 41 / 41_1–41_9.
  4. Add pin notes for strapping pins, UART GPIO aliases, and PSRAM-restricted pins.
  5. Keep the footprint/model naming consistent with ESP32-S3-WROOM-1-N8R8.
Overall: the symbol pin table appears correct, but the part project is not yet production-quality because footprint pad mapping is not fully verified and the electrical/sourcing metadata is incomplete.
