Built the first-pass RoadLog ELD Vehicle Module schematic and renamed/documented the project. It now contains 84 components and 50 nets, including protected 12/24 V truck power, BLE compute, J1939 CAN, legacy J1708 hardware, FRAM event storage, debug/service connections, indicators, and test provisions.
The Project Specification records the phone-first architecture, initial power budget, offline resilience, fleet-plugin direction, and the boundary between this board and full FMCSA compliance.
Open items
Independently inspect the executor’s completed wiring and resolve any ERC/connectivity findings.
Confirm every automotive protection and power-stage rating against its selected-part datasheet.
Validate J1708 behavior and the ignition/tamper-event sensing path.
Create firmware pin mapping, secure event-storage behavior, and the mobile/cloud compliance specification.
Complete schematic review before moving to PCB placement and routing.
FMCSA compliance still requires the complete app/cloud system, data-transfer workflows, malfunction handling, documentation, testing, self-certification, and registration.
