Protect timeline 2 working days max Project max 100cdn have a working RF receiver board with stable firmware, but the companion transmitter board is unusable because the only Gerber and BOM I was sent are corrupted. The transmitter’s firmware binary is intact, so the new hardware must accept that code without modification and still communicate flawlessly with the existing receiver over our RF data-transmission link. What I can supply: • The corrupted Gerber and BOM as rough references • High-resolution photos of the original populated transmitter board • The receiver board’s schematic and dimensions • The compiled transmitter firmware (HEX) Your task is to recreate the complete transmitter design from the ground up—clean schematic, PCB layout, production-ready Gerbers, pick-and-place files, and an updated BOM—so it drops straight into manufacture and works first time with the current firmware on both ends. Acceptance criteria: • DRC-clean Gerbers that open error-free in KiCad or Altium • BOM with current part numbers and at least two viable suppliers for key components • Proven impedance-matched RF path and antenna interface consistent with the receiver’s expectations • Design walkthrough followed by successful firmware load and on-bench communication test between new TX prototype and existing RX board If you’re comfortable reverse-engineering from limited documentation and have solid RF layout experience, I’d love to get this board back into production quickly.

Hello, I can help reverse-engineer and recreate the transmitter board from the available photos, corrupted Gerbers/BOM, receiver documentation, and existing HEX firmware. I have 10+ years of experience in PCB design, embedded hardware, RF/wireless systems, and reverse engineering, with strong experience in KiCad and Altium. I can recreate the schematic, PCB layout, RF path, antenna interface, Gerbers, drill files, Pick-and-Place, and updated BOM while keeping the hardware compatible with the existing firmware. I will also verify footprints, component availability, RF routing/impedance requirements, and run DRC before delivery. Timeline: maximum 2 working days. Fixed budget: CAD $100. One important point: because the transmitter firmware is compiled, I would first identify the MCU, clock, GPIO/peripheral assignments, RF IC, and programming requirements from the board and available documentation. This is essential to ensure the recreated hardware can run the existing HEX without firmware modification. I’m ready to review the supplied files and photos immediately.

⭐⭐⭐⭐⭐ I understand the key requirement here: the replacement transmitter must be recreated from incomplete/corrupted documentation while remaining fully compatible with the existing HEX firmware and receiver. I can work from the original board photos, corrupted Gerbers/BOM, receiver schematic/dimensions and firmware to reconstruct the schematic and PCB, paying particular attention to MCU pin mapping, clock/reset circuitry, power rails, programming interface and the complete RF signal path. My priority will be getting a manufacture-ready design without changing anything the existing firmware depends on. I’ll also verify RF routing/impedance and antenna interface against the receiver requirements, then prepare: • Clean schematic + PCB layout • DRC-clean Gerbers • Pick-and-place files • Updated BOM with current parts and alternative suppliers • Design walkthrough and concise hand-off documentation I can target the requested 2-working-day maximum and 100 CAD budget, provided the supplied photos/reference material contain enough information to confidently identify the components and connections. If you send the source files and board photos, I can start immediately by mapping the hardware required by the HEX.

Hi, I can deliver your board as a complete, manufacturing-ready package — schematic, multilayer layout, and all production files — without the usual back-and-forth between designer and fab house. I have 14+ years of experience in PCB design and firmware development. I work daily in Altium Designer, KiCAD, and Eagle, and I own licenses for Altium and Eagle, so I can start immediately on your project. My background covers: • 2–16 layer PCB layout, high-speed routing, and controlled-impedance design • Mixed-signal boards, power distribution, and EMI-aware placement • Full deliverables: schematic, PCB layout, BoM, Gerbers, pick-and-place, ODB++, assembly drawings, DRC report, and 3D STEP model I previously worked at READA PCB Technology in Shenzhen as a PCB designer and production manager. That factory-side experience means my layouts are built for real manufacturing — correct clearances, sensible via strategy, and DFM/DFA checks before files go out the door. If you also need prototypes or small-batch assembly, I can coordinate PCB fabrication, PCBA, component sourcing, functional testing, and shipping through the Shenzhen network I know well from my time at READA. I am available to start right away and happy to sign an NDA before reviewing your design brief. Looking forward to your reply. Best regards, Ting

I can help you turn a corrupted file set and a firmware binary into a production-ready transmitter. My approach is straightforward: I will treat the compiled HEX as the fixed system constraint and reverse-engineer the hardware around it. Using your photos for component placement and the receiver schematic for the RF interface expectations, I will derive the necessary electrical characteristics (like the oscillator frequency and modulation scheme) from the firmware binaries. I will rebuild the schematic from the ground up, focusing on the RF path layout to ensure a proper 50-ohm impedance match to the antenna, matching the receiver's interface. The deliverables will include a clean BOM with current, sourced parts from at least two suppliers for critical items to prevent future obsolescence issues. I understand that the only true test is physical. My goal is to provide you with a design that loads the existing firmware and allows us to validate the link during the bench test, ensuring it communicates flawlessly with the existing receiver, exactly as your acceptance criteria require.
