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.

Schematic is Auto-placed

The schematic has been arranged automatically. Flux can redraw it to be more readable, with components placed in related groups and wires drawn more legibly. This takes about 10-60 mins.

RF Integration Notes — ESP32 Smart City Controller
  • Place U1 so its PCB antenna is at or beyond a carrier-board edge and faces outward.
  • Keep copper, traces, vias, components, and ground pours out of the exact antenna keepout specified by the populated DevKit/module datasheet on all layers.
  • Keep J1-to-J3 servo power and return routing away from the antenna and analog inputs.
  • Do not place C1 or other tall components near the antenna.
  • Confirm the exact ESP32 module revision and certification IDs before product labeling.
  • Any enclosure material, nearby metal, external antenna, or module substitution requires renewed RF assessment.
