Having spent a considerable amount of time in the domain of Electrical Engineering, Electronics, and Embedded Systems, I believe my skillset perfectly aligns with your project needs. My proficiency in PCB Layout specifically with popular design tools like KiCad, Altium, and Eagle should allow me to create precise and accurate digital files for your ESP32-based board, ensuring it matches the original footprint and connector locations as closely as possible. In addition to these skills, I have extensive experience in reverse-engineering hardware designs and delivering production-quality infrastructure. My broader knowledge of building IoT hardware will significantly add value to your project as it involves preserving 'the same ESP32 microcontroller','on-board sensors/peripherals', and the original power-supply architecture.' With your provision of 'high-resolution photos', 'measurements', and if needed, the physical board itself for probing, I can meticulously capture these details and deliver an editable schematic file, PCB layout files, Gerbers/NC drillfiles, and a bill of materials with part numbers.

Good day. As i see, board has only two layers. I can done thisk in few days. Target price will be about 25000 INR. It will be enough to take more photos and measure some distances. For this task i prefer KiCAD.

Hello, I have strong experience reverse-engineering ESP32-based hardware and recreating complete schematic and PCB design files from existing boards for production use. I understand that this type of work involves more than visually copying the PCB. The main challenges are accurately reconstructing hidden connections and power distribution, preserving ESP32 boot/flash behavior, maintaining antenna and RF performance, identifying onboard sensors/peripherals, and reproducing the original layout while keeping manufacturing reliability. I have experience with ESP32 hardware, mixed-signal PCB layouts, programming headers, power-management circuits, and RF-sensitive routing. I can work from high-resolution photos, measurements, continuity checks, or the physical board itself if deeper analysis is required. My workflow includes schematic reconstruction, footprint verification, PCB recreation, BOM preparation, and fabrication-ready output generation. I primarily use KiCad and can deliver editable project files, Gerbers, NC drill files, BOM with sourcing suggestions, and concise design notes. I carefully reviewed your requirements and fully understand the validation process regarding continuity matching and Gerber overlay comparison. I am confident I can take this project from reverse engineering to production-ready deliverables without issues. Please share the board photos and available details so I can evaluate the complexity and begin immediately. Best regards Jude

You can use this edited version mentioning Altium naturally: Hi, This is exactly the kind of reverse-engineering work I regularly handle with ESP32 hardware, and I’m confident I can recreate the board accurately from the physical unit/photos while keeping the original functionality and footprint intact. I work primarily in Altium Designer and can deliver fully editable project files along with fabrication-ready outputs. My process includes continuity tracing, component identification, power-path verification, connector mapping, and PCB recreation with close mechanical alignment to the original board. Deliverables include: * Editable schematic and PCB files * Gerbers + NC drill files * BOM with manufacturer part numbers * Design notes and assumptions/improvements I also pay close attention to ESP32 RF layout, antenna clearance, programming headers, mixed-signal routing, grounding, and power integrity. Once I review the board photos, I’ll confirm turnaround time and whether the physical board is needed for deeper probing or hidden-layer validation. Please send the photos/measurements whenever ready.

Hi, Reverse-engineering existing PCBs into clean, reproducible design files is something I do regularly — ESP32-based boards in particular, since I work extensively with that platform across IoT and embedded projects. This is a well-defined scope and I am confident I can deliver files you can immediately build from and modify. Starting from your photos and measurements, I will trace every net — power rails first, then ESP32 peripheral buses (SPI, I2C, UART, GPIOs), then sensor/peripheral connections — cross-referencing component markings against datasheets to confirm values and pinouts. Anything ambiguous from photos alone gets flagged early before it is committed to the schematic. For the layout I will respect your original footprint envelope and connector positions, with proper antenna clearance and solid ground-plane practice under the mixed-signal sections. Any minor improvements made will be documented in the design notes — nothing that changes function. I work in Altium. Deliverables: Complete editable schematic in Altium PCB layout + Gerbers and NC drill files, fab-ready Full BOM with part numbers and sourcing (LCSC/Mouser/DigiKey) Design notes covering every assumption and improvement Your acceptance check — net-by-net continuity match and Gerber overlay against your reference images — is exactly how I validate the work myself before delivery, so we are fully aligned. What is your timeline for having Gerbers ready to send out?

Hi, This is a project I can help with. I have experience reverse-engineering embedded hardware, including ESP32-based designs, and can recreate the schematic, PCB layout, and manufacturing files from an existing board. For this project, I would use KiCad (preferred for fully editable, license-free deliverables), though I can also work in Altium if required. My approach would be: • Analyze the provided photos, measurements, and board details to identify all components and connections. • Reconstruct the complete schematic, preserving the ESP32 device, peripherals, sensors, and power architecture. • Recreate the PCB layout to closely match the original footprint, mounting holes, connector positions, and RF considerations. • Generate fabrication-ready Gerbers, drill files, BOM, and assembly notes. • Document any assumptions, unidentified components, or recommended improvements. Before starting, I would like to review high-resolution images of both PCB sides, dimensions, layer count (if known), and any available information about the ESP32 variant and connected peripherals. If some traces are inaccessible from photos, receiving the physical board for probing would help ensure complete netlist accuracy. I’m happy to review the board photos and provide an initial assessment of complexity, expected turnaround time, and any potential challenges.
