Project description:
"We are building a real-time in-car fuel cost tracker that plugs into any vehicle's OBD-II port. The device uses an M5Stack Core2 microcontroller to read engine data via CAN bus, calculate live trip costs in EUR (like a taxi meter), and track CO2 emissions—all without draining the car battery. It automatically logs trips, maintains a multi-year history, and exports data to microSD as CSV for tax or fleet analysis. The prototype must survive automotive thermal extremes, power loss, and frequent starts/stops. This is market validation for a consumer product targeting the 95% of drivers who want real cost visibility but won't install complex diagnostics. Success is measured by accuracy within 10% after one calibration fill-up, zero data loss through 50 abrupt power cuts, and deep sleep at 2 mA or less." (client-provided description)

Additional information:"Real-time money display: live trip cost ticking up, distance, average cost/km. CO2 tracker: grams emitted per km. Full-cost indicator: including wear, maintenance, insurance estimate (default 0.55 EUR/km, user-editable). Automatic trip start/stop via engine detection. Refuel calibration: user logs fill-ups to improve long-term accuracy. Multi-level history: trip-by-trip, daily, weekly, monthly, custom date range. CSV export to microSD. Settings: fuel price, fuel type, currency, full-cost rate. Ultra-low power sleep mode. Touchscreen UI with clear, large digits." (admin-provided information)
