Created and verified the complete ESP32 Smart City Controller schematic, including HC-SR04 level shifting, servo stabilization, analog inputs, and six LED channels. Documentation: Project Specification, Power Budget, Firmware Starter, and Bring-Up Plan.
  • Open item: ERC reports U1:VP as an unpowered supply due to an incorrect library pin classification; VP is actually unused GPIO36 and is correctly marked no-connect.
  • Next: confirm the servo model/stall current, then configure the board and place components with antenna keepout and wide 5 V/ground paths.

hay un capacitor que no esta donde deveria estar ponlo en su lugar

flux

Claro — necesito que me indiques cuál capacitor y dónde debería ir.
Puedes responder con algo como:
  • “C1 debe ir junto al conector del servo J3”
  • “C3 debe ir cerca del pin 5V del ESP32”
  • “El capacitor cerca de la esquina inferior derecha debe ir junto a U1”
Si puedes, selecciona el capacitor en Flux o dime su designador (C1, C2, C3, C4 o C5) y lo muevo a su lugar.

ya lo tengo seleccionado

flux

Perfecto, revisaré el componente seleccionado y lo recolocaré donde corresponde según su función en el circuito.

flux

Listo. Moví C1 junto al conector del servo J3, manteniendo el resto de los componentes en sus posiciones. Verifiqué que quedó dentro de la placa y sin solapamientos.

  • Accredited EMC/RF test reports as required.
  • Final antenna keepout verification from PCB layout.
  • Final labels, enclosure photographs, and production user manual.
Integration Conditions
  • Preserve the ESP32 module antenna keepout on every copper layer.
  • Do not place the servo/current loop near the antenna.
  • Use the approved module antenna configuration; external antennas require separate review.
  • Retest if the module, antenna, enclosure, ground plane, or firmware radio settings change.
