PCB Tracer is a browser-based tool for PCB reverse engineering, troubleshooting, and repair. It is designed for situations where no schematic is available: users import photos of both sides of a circuit board, align them using transparent overlays, zooming, rotation, and panning, and then progressively annotate traces, vias, pads, and components. Its core value is not merely βdrawing lines on an image,β but converting annotations into a structured circuit model with connectivity relationships.
The tool uses a unique NodeID to manage each via, pad, pin, power node, ground node, and test point. Traces can snap to nodes, enabling network tracking across layers. It provides 17 tools and 14 layers, making it easier to separately control front and back photos, traces, pads, components, buses, and test points. Its AI capabilities are fairly broad: it can extract IC types, pin names, packages, and other information from PDF datasheets to generate dedicated IC objects; identify components based on markings, photos, and context; generate netlists with logical names such as VCC_5V and CLOCK_IN; and produce circuit explanations, troubleshooting suggestions, and expected DMM readings. It also supports BOM export to JSON/PDF, as well as KiCad schematic export in beta.
The main text does not disclose pricing, free quotas, subscription options, payment methods, or commercial licensing. It also does not state whether the product is open source. The page says it βRuns locally in the browserβ and requires βNo installation,β but it also mentions AI analysis and database cross-referencing in several places. It is not clear whether this data is uploaded to the cloud, nor whether self-hosting or offline deployment is supported.
Its strengths are its clear positioning, especially for repairing boards without schematics, restoring older equipment, and analyzing unknown circuits. The NodeID model is better suited than ordinary drawing or image annotation for later netlist generation, BOM creation, and fault analysis. KiCad export also improves integration with the open-source EDA ecosystem. The downsides are the lack of key commercial and privacy information, the fact that KiCad export and troubleshooting are still in beta, and that AI results depend heavily on photo quality, the completeness of manual annotation, and the quality of component documentation.
PCB Tracer is suitable for repair engineers, hardware reverse engineers, electronics hobbyists, and teams that need to organize board-level documentation. The main text does not provide information about access from China, so real-world network connectivity, AI feature availability, and payment support still need to be tested. If access is limited, alternatives such as KiCad, EasyEDA, or traditional EDA tools combined with manual annotation workflows may be considered, though these options are generally not focused on photo-level reverse tracing.
