Phase 1 (schematics only) - Industrial Embedded Product Redesign (EasyEDA)

@amelectronics

Hello, I’m interested in your project and would be happy to work on the schematic revision and continue with the PCB layout in the next phase. I have experience with embedded hardware design, mixed-signal PCB design, ESP32 and STM32-based systems, RS-485 communication, isolated power supplies, and industrial interfaces. I’m comfortable reviewing and modifying existing designs created by other engineers and ensuring the schematic is ready for production. Thank you.

Hi there, I read your offer carefully and understand that you need Phase 1 schematic revision for an existing EasyEDA industrial embedded product, with component replacements, footprint updates, LCD connector addition, DNP review, ERC cleanup, and preparation for PCB layout. I can review and update the existing EasyEDA project, verify power/signal/communication connections, correct symbols and footprints, document all changes, mark DNP components, and make the schematic ready for the next PCB layout milestone. My experience with industrial electronics, mixed-signal hardware, isolated power supplies, RS485, ESP32/STM32 systems, precision analog routing, EMI/EMC-aware design, and production-ready PCB documentation fits this project well. Just send me a message and we can review the existing EasyEDA files and start with the schematic revision. Best regards, Samuel Tshibangu

I am an Embedded Systems and PCB Design Engineer with experience in Altium Designer, Kicad, Easyeda, Protious and custom hardware development. I can design your PCB from schematic to production-ready files, including: • Schematic Design • PCB Layout • Component Selection • Design Rule Check (DRC) • Gerber Generation • BOM Preparation • Manufacturing Support (JLCPCB, PCBWay, etc.) I have experience with ESP32, STM32, sensor interfaces, power supplies, RF modules, Ethernet, and industrial electronics. Please share the project requirements, schematic (if available), board dimensions, and any special requirements. I can start immediately. Looking forward to working with you.

I have 5.5+ years of experience in industrial hardware design, including schematic review, PCB design, mixed-signal layouts, isolation techniques, and EMI/EMC-aware designs. I can revise your existing EasyEDA schematic, update components, verify the design, and prepare it for a reliable PCB layout. I'm comfortable working on existing projects and would be happy to support this as a long-term collaboration.

Your existing EasyEDA schematic with isolation domains is exactly the kind of project I enjoy working on. I’ve spent the last six years designing industrial boards with isolated analog front ends, RS-485, and mixed-signal layouts, so this feels like a natural fit. Here's what I bring to this: → I’ve delivered three industrial sensor transmitter boards with galvanic isolation and 4–20 mA outputs, all done in EasyEDA → I’m experienced with swapping components and updating footprints while keeping the schematic clean and consistent → I can handle the full stack — schematic revision, PCB layout with isolation and DFM, and even firmware if needed later → I’m available to start immediately and can complete the schematic review and updates within a 5 days. For the schematic revision milestone, the cost would be 1050, and I’m happy to walk you through the changes in a quick chat. Looking forward to collaborating long-term.

Hi, Please check my portfolio — I have designed several industrial mixed-signal PCBs in EasyEDA featuring ESP32 and STM32 microcontrollers, digital isolators, and isolated DC-DC supplies. I can review your existing EasyEDA schematic, integrate the new 7-pin SPI/I2C LCD module, update footprints, and establish clear DNP component lists. Once ERC passes, I will handle Phase 2 PCB layout focusing on AGND/DGND separation, creepage clearance, and EMI-aware routing for JLCPCB manufacturing. I am completely comfortable taking over existing EasyEDA projects and look forward to a long-term collaboration. Best regards,

Hello, I have experience in both KiCad and EasyEDA, and I have worked on embedded hardware and PCB design projects involving ESP32, STM32, ATmega, RS-485, power supply circuits, and mixed digital/analog interfaces. I can review your existing EasyEDA schematic, replace components, update symbols and footprints, add the LCD interface, verify all power and communication connections, prepare the DNP list, and ensure the design passes ERC before moving to PCB layout. I am comfortable working on projects created by other engineers and can maintain proper documentation throughout the revision process. During the PCB phase, I will pay close attention to component placement, grounding strategy, isolation requirements, and manufacturability to achieve a reliable industrial design. I would be happy to discuss the project in more detail and review the existing EasyEDA files before we begin. Thank you for your time, and I look forward to working with you. Best regards, Sathishkumar N Embedded Systems & PCB Design Engineer

I would appreciate the opportunity to work on your industrial embedded hardware project. I have experience reviewing and updating existing schematics, redesigning mixed-signal circuits, and preparing hardware for reliable PCB implementation. I am comfortable working with EasyEDA projects created by other engineers and can efficiently modify symbols, footprints, libraries, and component selections while maintaining design integrity. For Phase 1, I will thoroughly review your schematic, replace the required components, integrate the new LCD interface, verify all power and communication paths, perform ERC checks, and prepare a detailed list of design changes and DNP components so the design is fully ready for PCB layout. I understand the importance of isolation, creepage and clearance, grounding strategy, EMI/EMC considerations, and precision analog routing in industrial products. My experience includes embedded hardware based on STM32/ESP32, RS-485 interfaces, isolated power supplies, digital isolation, and mixed-signal circuit design. I am committed to delivering accurate, well-documented work on time and would be pleased to continue with Phase 2 PCB layout and future hardware revisions as a long-term collaborator.

Hi, I hope you're doing well. I've delivered several schematic revisions and worked with mixed-signal industrial designs in EasyEDA. On a recent project I replaced a Murata isolated DC-DC with a TE/Coilcraft part and swapped TI ISO7741 digital isolators while adding a 7-pin SPI LCD, handling footprint changes and ERC fixes. I'd start by reviewing the EasyEDA project, update symbols/footprints, run ERC and a net-by-net power/signal check, and mark DNP items. If you have ten minutes, I'd like to compare notes on the LCD interface choice (SPI vs I2C) and any preferred isolator families. Thank you, habib Niazi

IF YOU'RE NOT HAPPY, YOU DON'T PAY. I recently completed a schematic revision for an industrial embedded product, resulting in a streamlined design that improved signal integrity and reduced component costs. I understand your need for modifications to the existing EasyEDA schematic, including component replacements and the addition of a new LCD module. I will ensure that the design is clean and efficient while verifying all connections and identifying components that should not be populated on the PCB. My focus will be on maintaining high standards for mixed-signal design and ensuring compliance with isolation and power supply requirements. I prioritize good planning, clean and maintainable code, clear communication, on-time delivery, and reliable long-term solutions. I am ready to help you achieve a successful redesign. If this aligns with your project, feel free to reach out to discuss scope and pricing. WORST CASE SCENARIO YOU WALK AWAY WITH A FREE CONSULTATION. Regards ridwaan6254
