Hola, te explico el proyecto para que tengas claro qué está hecho y qué es lo que realmente necesitamos corregir. No es hacer toda la PCB desde cero. Ya existe un trabajo desarrollado en KiCad y la idea es partir de esos archivos y corregir únicamente la parte que quedó pendiente. La persona que trabajó anteriormente desarrolló el diseño de la PCB y dejó los archivos del proyecto, esquemático y layout. El problema señalado por el cliente está principalmente en U1, que corresponde al módulo ESP32. El cliente quería sustituir el ESP32 NodeMCU que utilizaba originalmente por una versión personalizada utilizando el ESP32-WROVER-IE (C701351). La corrección que necesitamos hacer es que ese nuevo módulo personalizado realmente funcione como reemplazo del NodeMCU ESP32 v1.1. Es decir: - Utilizar el ESP32-WROVER-IE como microcontrolador. - Crear/ajustar la implementación propia del módulo en lugar de simplemente utilizar el módulo NodeMCU como U1. - Mantener las medidas físicas de referencia del NodeMCU ESP32 v1.1. - Mantener la distribución y posición de los pines para que el nuevo módulo pueda ocupar la misma posición y conservar las conexiones que correspondan. - Revisar las conexiones de U1 para asegurarnos de que sean correctas con el WROVER-IE. - Revisar el footprint, dimensiones y ubicación de los pines. - Hacer solamente los cambios necesarios en la PCB alrededor de U1 para que el reemplazo sea correcto. Hay una aclaración importante del cliente: el PDF de la PCB existente no era una instrucción para rediseñar toda la placa. Lo proporcionó como referencia para saber dónde estaba colocado el NodeMCU, qué espacio había disponible alrededor y qué conexiones llegaban a él. Por eso no necesitamos rehacer toda la PCB ni cambiar componentes que ya están correctamente diseñados. El objetivo es tomar el trabajo existente, revisar U1 y hacer la corrección necesaria para que el ESP32-WROVER-IE sea realmente una versión personalizada compatible físicamente y eléctricamente con la posición que ocupaba el NodeMCU. Los archivos originales de KiCad y las referencias del proyecto te los puedo proporcionar. Lo ideal es que primero revises lo que ya está hecho y me confirmes qué cambios puntuales necesita U1 antes de modificar otras partes. En resumen: el 90% del trabajo ya está realizado; necesitamos corregir la implementación del ESP32-WROVER-IE para que cumpla exactamente con las características de dimensiones, distribución de pines y conexiones que tenía que conservar del NodeMCU. No es un diseño nuevo desde cero.

Hola, he revisado su descripción y el alcance está claro: no se trata de rehacer la placa, sino de corregir U1 para que el ESP32-WROVER-IE funcione como reemplazo físico y eléctrico del NodeMCU ESP32 v1.1. Puedo revisar los archivos de KiCad, validar el footprint, dimensiones, posición de pines y las conexiones de U1 para aplicar únicamente los cambios necesarios alrededor del módulo. Mi enfoque sería respetar la huella mecánica existente, verificar la compatibilidad del circuito y ajustar el esquemático/layout sin alterar el resto del diseño. Trabajo habitualmente con Electronics, Electrical Engineering, PCB Layout y Embedded Systems, por lo que este tipo de corrección puntual encaja bien con mi perfil. Si le parece, reviso primero el proyecto y le indico exactamente qué debe modificarse antes de tocar otras áreas. Quedo atento para avanzar con ¿Podría compartir los archivos de KiCad y, si existe, el pinout esperado para confirmar la compatibilidad física y eléctrica de U1?. Saludos, Miguel

Perfecto, gracias por la aclaración. Ahora el alcance está completamente claro. Entiendo que el objetivo no es rediseñar la PCB principal sino revisar específicamente la implementación actual de U1 y verificar que el ESP32-WROVER-IE sea compatible física y eléctricamente con el ESP32 NodeMCU v1.1 utilizado como referencia. Mi primer paso será revisar los archivos de KiCad existentes, comparar el diseño actual con los requisitos del NodeMCU y elaborar una lista de las correcciones necesarias antes de modificar el proyecto. Revisaré pin mapping, circuito de arranque, alimentación, footprint, dimensiones mecánicas, restricciones de antena y compatibilidad con las conexiones existentes. Una vez completada la revisión, te informaré exactamente qué cambios necesita U1 y después realizaré únicamente las modificaciones relacionadas con esa parte del diseño.

Hello, I can review and correct the existing KiCad design specifically around U1 without unnecessarily redesigning the rest of the PCB. I have hands-on experience with ESP32-based PCB designs, KiCad, custom footprints, schematic/PCB consistency checks, and component placement. For this task, I will first review the existing KiCad files and compare the current NodeMCU implementation with the ESP32-WROVER-IE requirements. I can then: • Verify the ESP32-WROVER-IE pinout and required supporting connections • Review and correct the schematic implementation around U1 • Verify/create the correct footprint and physical dimensions • Preserve the required NodeMCU reference position and pin arrangement where electrically possible • Update only the necessary PCB routing around U1 • Check power, enable/reset, boot/programming and related ESP32 connections • Run final ERC/DRC checks Before modifying the PCB, I can first identify and explain the specific issues I find around U1, as requested. I am available to start with the existing KiCad project files and hardware references. Best regards, Hamza El Amraoui

¡Hola! Puedo revisar el proyecto existente en KiCad y corregir específicamente la implementación de U1 para que el ESP32-WROVER-IE funcione como reemplazo del NodeMCU ESP32 v1.1, sin rehacer la PCB completa. Revisaré el esquemático, footprint, dimensiones, distribución de pines, conexiones eléctricas y el espacio disponible alrededor de U1 para identificar exactamente qué debe modificarse y mantener el resto del diseño intacto. ¿Podrías compartir los archivos originales de KiCad y las referencias del ESP32-WROVER-IE para revisar primero el diseño actual? Recientemente, he trabajado con diseño y revisión de PCB, integración de microcontroladores y corrección de esquemáticos/layouts en KiCad, prestando especial atención a footprints, pin mapping, restricciones mecánicas y conexiones eléctricas. Puedo partir directamente de los archivos existentes y realizar únicamente los cambios necesarios para conseguir una integración limpia y compatible con las dimensiones y conexiones requeridas. Best, Ariba

Dear Client, For an ESP32-WROVER-IE PCB correction, the biggest risk is not redesigning the board—it is replacing the existing NodeMCU implementation while preserving the required footprint, pin positions, electrical connections and mechanical compatibility. I have 11+ years of electronics/PCB experience across 500+ assignments involving ESP32, IoT hardware, KiCad, custom modules, PCB layout, schematic review and prototype bring-up. My development path would be: Existing KiCad Files → U1 Review → WROVER-IE Schematic → Footprint/Pin Verification → PCB Update → ERC/DRC I would focus specifically on U1 and make only the necessary changes, keeping the existing PCB architecture, dimensions and correctly designed components untouched. I can review the existing KiCad schematic/layout, verify the ESP32-WROVER-IE connections and footprint, maintain the NodeMCU reference dimensions/pin arrangement, update the surrounding PCB and provide the corrected editable KiCad files. Two important questions: 1. Can you provide the existing KiCad project and WROVER-IE datasheet/reference? 2. Is the NodeMCU pinout/physical dimension the exact compatibility target? Profile: https://www.freelancer.in/u/ElectronicsMust If you message me, I’ll first review U1 and identify the exact changes required before modifying the PCB. Kind Regards, Avi Gupta Quality is never an accident

Hi, I can quickly fix and convert U1 from NodeMCU v1.1 to a custom ESP32-WROVER-IE (C701351) setup directly on your KiCad PCB. How I will handle this: 1. Replace the NodeMCU footprint with ESP32-WROVER-IE 2. Add the required minimal system components 3. Verify trace clearance, antenna keepout zone, and run full KiCad DRC/ERC checks. I can review your KiCad files immediately and finish the correction within a few hours. Looking forward to working with you!
