Automotive Signal Unit km to miles
Budget: $250 – $750 USD
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 (
