Schematic diagram from Circuit Board

Hi There, I am a senior electronics design engineer with a decade experience in the field. I can reverse engineer the board you provided and come up with a complete circuit connection. This type of task is not new to me. I have like this in the past. All I need in the reverse engineering is the very clear picture of the board (to and bottom) in such a way the traces are visible. I am an experience engineer, do I will know if the circuit I made make sense or not. Looking forward in working with you.

Hi I am a post graduate power electronics engineer and having very good experience in product design and development . I am excellent in products design, circuit design and schematics preparation for products like power supplies, control circuits , gate drive cards, Microcontroller card circuits etc. I am ready to work for you. Please contact me for further discussion.

Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, Library creation and Library database maintenance, PCB Manufacturing, Component procurement, PCB Assembling and Functional testing for over 9 years. I have used various CAD/EDA tools for PCB design. Would you prefer any specific EDA tool for PCB design (or) any tool is okay? I will provide the PCB Manufacturing, Component procurement, PCB Assembling & Functional testing services too. I look forward to hearing from you! Wish you a nice day! Thanks & Regards, Karthik

Hello, Please provide real photos of the module. I am concerned that the two ICs have their code erased. If this is the case, the reverse engineering process is next to impossible. Denting on this information, I can upgrade my bid. Thank you.

I’m an electrical engineer of 20+ years in the scientific instrumentation field with experience in EDXRF, Immunofluorometers, and gas chromatograph mass spectrometers. I’ve been involved in all aspects of system and board design throughout my career. My strengths are in analog, documentation, and regulatory. I am new to freelancing and am enjoying it. To date I’ve done two jobs. 1 - strobing LED board for use in a self-defense weapon. 2 - Update a schematic using KiCad to add in a LAN circuit. I have partners that can help me with areas where I am less skilled. I would love to work on this schematic for you. I can do it easily with KiCad or EagleCad. For additional cost I can do it in OrCAD.. Do you have a physical sample of the board that I can use as I reverse engineer the schematic? Actually, don't worry about that. If I win the bid I can get a board from Amazon or eBay for cheap. This should be a piece of cake.

Hello sir, I can help you to finish your job. I have experience in electronics 20 years. All this time I work automation project like modification old machine replace with another automation control. So I hope you have time to contact or discussion with me. Thank you.

Completed project as soon as possible. Experienced in reverse engineering.

I am working at software house. I am professional in it

Hi, I need sample device/part to do this reverse engineering. Let me know if you need more details...

I need the board to capture the schematic.
