ESP32 Smart City Controller
Thought for 7 sec
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

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

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.

Power Budget — ESP32 Smart City Controller
Estimated Loads
Table
| Rail | Load | Typical | Peak / Design Case | Basis |
|---|---|---|---|---|
| 5 V input | ESP32 DevKitC including Wi-Fi bursts and onboard regulator | 250 mA | 700 mA | conservative module/board allowance |
| 5 V input | HC-SR04 | 15 mA | 20 mA | common module operating range |
| 5 V input | Hobby servo | 500 mA | 1.8 A | assumed micro-servo; verify actual stall current |
| 3.3 V via DevKit | Analog microphone module | 5 mA | 10 mA | module-dependent assumption |
| 3.3 V GPIO | Six LEDs | 36 mA | 45 mA | about 6 mA/channel with red LEDs and 220 Ω |
| 3.3 V | Potentiometer | 0.33 mA | 0.33 mA | 10 kΩ across 3.3 V |
Totals
- Estimated typical 5 V source current: approximately 0.81 A.
- Estimated peak with micro-servo stall and Wi-Fi burst: approximately 2.58 A.
- Recommended supply: regulated 5 V, 3 A.
- Minimum for a characterized low-current micro-servo: regulated 5 V, 2 A.
Power-Path Sizing
- J1 is rated well above the 3 A design target.
5V_EXTandGND: design for 2 A continuous / 3 A peak.- PCB layout: at least 0.5 mm / 20 mil traces as requested; use wider pours/traces for J1-to-J3 servo power and return where space permits.
- C1 470 uF provides local servo transient support; increase toward 1000 uF if bench testing shows resets or rail droop.
Open Assumption
The actual servo model is unspecified. Before manufacturing, replace the assumed 1.8 A stall current with the servo datasheet value and confirm the adapter, connector, copper, and capacitor sizing.
