Overview

FMB003 is an ultra-small plug-and-play device built for OBD applications. Its key feature is reading OEM parameters (PIDs) directly from the vehicle's OBD port, giving access to real odometer and real fuel level data — with a supported-vehicle list so you know in advance what data a specific vehicle exposes. It suits fleet management of light commercial vehicles, driver log-books, insurance telematics (UBI), and car rental & leasing.
