Hola, puedo encargarme de este diseño PCB en KiCad y entregar el proyecto completo listo para fabricación y ensamblaje en JLCPCB. Adaptaré la referencia NodeMCU ESP32 v1.1 al ESP32-WROVER-IE (C701351), incluyendo la alimentación 5V/3.3V, supervisor, doble bus I2C, DS3231, SD, GSM/RS232 y las interfaces externas. Revisaré los archivos y datasheets proporcionados antes de implementar el diseño, verificaré footprints y disponibilidad en LCSC, optimizaré el layout de 2 capas y realizaré el DRC final, Gerbers, Drill, BOM y CPL. Estoy acostumbrado a trabajar con restricciones mecánicas y entregas urgentes. Si encuentro alguna especificación o conexión que no esté clara, te consultaré antes de asumirla. Puedo comenzar inmediatamente.

Hola, He leído cuidadosamente todo el brief y entiendo que el objetivo es adaptar el diseño existente basado en NodeMCU ESP32 v1.1 al ESP32-WROVER-IE (C701351), manteniendo la compatibilidad necesaria, las restricciones mecánicas y preparando el proyecto completamente para JLCPCB. Antes de diseñar, revisaré MEGA_0.4.4_sch/pcb, mega_sd_0.1, imágenes y datasheets para determinar qué debe conservarse, modificarse o eliminarse. He considerado los puntos clave: entrada 5V/3.3V, supervisor C7719 y verificación WDI-TX, DS3231 con opción módulo/SMD e I2C independiente, SD módulo/SMD, segundo MCU, GSM, MAX232, relés, redistribución de GPIO del teclado y orientación del conector de antena. Realizaré esquemático, validación de componentes/footprints LCSC, placement mecánico, routing 2 capas, revisión de alimentación/GND, DRC y verificación eléctrica/mecánica final. Entregaré KiCad editable, Gerbers, Drill, BOM LCSC y CPL/Pick & Place. No asumiré ningún dato no definido: consultaré cualquier punto ambiguo antes de implementarlo. Puedo comenzar inmediatamente. Best regards, Hamza El Amraoui

I'll review your reference files and adapt the NodeMCU ESP32 v1.1 design in KiCad for the ESP32-WROVER-IE (C701351), preserving pin compatibility and mechanical clearances, with the antenna connector facing the required side. I'll run ERC/DRC checks and deliver KiCad sources, Gerbers, drill files, BOM, and placement files for JLCPCB. I can prioritize this urgent $90 project and confirm the delivery timeline after reviewing your files.

@peculiarduke123

El riesgo principal en esta PCB de 2 capas es el ruido del módulo GSM y la fluctuación de 3.3V al alimentar la SD y el ESP32-WROVER-IE simultáneamente sin planos de masa limpios. Para garantizar la entrega urgente de $90 USD lista para JLCPCB, el flujo de trabajo en KiCad será: Arquitectura de Alimentación & RF: Pistas de alimentación sobredimensionadas, desacoplamiento pegado a los pines del ESP32 y plano de masa continuo en la capa inferior sin cortes bajo la antena. Integridad de Señales: Bus I2C independiente para el DS3231 con sus pull-ups dedicadas, bus SD optimizado y verificación del pin WDI del supervisor LCSC C7719 a la línea TX. Layout Dual (SMD / Módulos): Footprints híbridos para montar el RTC y la SD como módulos de pines o componentes SMD directamente. Archivos JLCPCB: Esquema, PCB, Gerbers, Drill, BOM con Part Numbers de LCSC y CPL (Pick & Place) validados mediante DRC sin errores. ¿Tienes las dimensiones exactas de la PCB U1 o los archivos KiCad de origen para fijar las restricciones mecánicas hoy mismo? Envíame un mensaje y arrancamos.

Dear Client, For this ESP32 redesign, the biggest risk is not adapting the NodeMCU reference—it is preserving pin/mechanical compatibility while integrating the ESP32-WROVER-IE, RTC, SD, supervisor and external interfaces without creating RF, power or assembly problems. I have 11+ years of electronics/PCB experience across 500+ assignments, including 50+ ESP32-based designs, KiCad, low-power hardware, RTC/SD interfaces, power regulation and JLCPCB-ready manufacturing files. My development path would be: Reference Review → Pin Audit → Schematic Adaptation → LCSC/Footprints → Power/GND → Routing → DRC → JLCPCB Release I would focus on ESP32-WROVER-IE decoupling, antenna keep-out/orientation, 5V→3.3V stability, TX→WDI supervisor validation, dual RTC/SD implementations, GPIO reassignment, connector accessibility and clean 2-layer routing. I can support schematic adaptation, KiCad PCB layout, custom footprints, BOM/LCSC verification, Gerbers, Drill, CPL and final manufacturing review. Two important questions: 1. Must the NodeMCU pin positions remain exactly identical? 2. Is the SD interface currently SPI or SDMMC? Profile: https://www.freelancer.in/u/ElectronicsMust Kindly message me, I’ll tell you the first three electrical/mechanical conflicts I would verify before placement so the urgent redesign does not require another PCB revision. Kind Regards, Avi Gupta Quality is never an accident
