I need a full-stack hardware/firmware solution that converters can signal km to miles. The heart of the job is a custom, automotive-grade PCB paired with firmware that can switch between brand-specific profiles (using jumpers) while it performs real-time signal analysis, unit conversion—think km/h instantly shown as mph—and delivers the results over existing screen or dial Hardware The board must survive the harsh 12 V system, deliver rock-solid CAN transceiver performance. I will rely on you for the full schematic, layout, BOM, Gerbers, and production-ready documentation. Execute unit conversions Brand coverage for the first release: Toyota, Nissan, Honda (including early models), Mitsubishi, Suzuki, Mazda, Audi. Deliverables 1. Schematic, PCB layout files, Gerbers, and a verified BOM 2. Compiled firmware, full source, and build instructions 3. A sample set of vehicle profiles demonstrating each supported brand 4. Brief user documentation showing how to swap profiles and perform a sample conversion 5. Full multi-vehicle support, extended testing, production optimisation, enclosure/cable design, and final production validation can be handled in the next stages (

Hello, I can help design a complete automotive-grade hardware and firmware system that reads CAN signals, applies vehicle-specific profiles, and converts values like km/h to mph in real time. The solution would include a robust PCB designed for 12V automotive environments with proper protection, stable CAN transceiver integration, and support for jumper-based profile switching. Each profile (Toyota, Nissan, Honda, Mitsubishi, Suzuki, Mazda, Audi) can map signals differently without needing firmware reflashing. On the firmware side, I can build an embedded C/C++ system that handles real-time CAN parsing, signal decoding, and unit conversion logic while applying the selected brand profile dynamically. The architecture will be modular so it can be extended to additional vehicles later. Deliverables can include full schematic, PCB layout, Gerbers, BOM, production files, firmware source code, compiled builds, sample vehicle profiles, and clear documentation for setup and testing.
