Hi, I have extensive experience designing industrial control systems and I am ready to complete your ESP32-S3 board directly within Flux.ai. I will implement robust opto-isolation for your six high-side outputs and digital inputs, ensuring they handle 24V industrial environments with proper TVS and flyback protection. My design will feature the MCP23017 for efficient I/O expansion and precise 0 to 10V analog scaling for your ESP32 ADC. I will ensure all components are sourced from Digi-Key for immediate availability and provide a clean, DRC-validated layout within your ten-day deadline. I look forward to delivering a professional, manufacturable solution for your project. Best regards

✅✅✅ Industrial ESP32-S3 PCB Design Engineer (24V Systems) ✅✅✅ Hi there, I have strong experience designing 24V industrial interface boards with opto-isolated inputs, high-side PMOS/PNP outputs (500mA+), TVS/surge protection, and robust power front-ends (5–36V). I’ve developed ESP32-based control boards with MCP23017 expansion, 0–10V analog I/O, and proper EMC-conscious layouts for noisy environments. My approach is to architect a protected 24V input stage (reverse polarity, surge, TVS), clean regulation for logic rails, and isolated, high-side sourcing outputs with individual flyback and snubber networks. I’ll ensure clean grounding, ADC stability, level shifting for Neopixel, Digi-Key-verified BOM, and DRC-clean manufacturable Gerbers in Flux.ai. Questions: Required PCB size constraints? Target layer count? Isolation voltage target for optos? I am ready to start immediately. Best regards

Hi There, I understand that you are looking for an experienced PCB designer to develop a custom industrial control board based on the Waveshare ESP32-S3-ZERO-M. I can assure you that I possess the necessary skills and experience for this project, having worked on several designs featuring opto-isolated high-side switching and industrial-grade components. With over 6 years in electronics, industrial design, embedded systems, and PCB layout, I am confident in delivering a schematic and layout that meets your specifications. My experience with the MCP23017 I2C I/O expander and providing robust protection for industrial circuits aligns perfectly with your project requirements. Here are some relevant portfolio links showcasing my prior work: - https://www.freelancer.com/u/haseebsidd07 I look forward to collaborating with you on this exciting project and meeting your deadline. Thank you, Regards, Abdul Haseeb Siddiqui

I specialize in industrial 24V PLC-style interface boards and have delivered opto-isolated input/output designs with high-side PMOS switching and robust field protection networks. Integrating the Waveshare ESP32-S3-ZERO-M with an I2C expander such as the MCP23017 is straightforward, and I will ensure stable I2C routing, analog filtering for 0–10V scaling, and low-noise ADC referencing. My layouts prioritize creepage, return current control, and EMI resilience. I can meet the 10-day timeline and deliver production-ready Gerbers and a complete Digi-Key BOM with no long lead-time parts.
