OBD adapters (sometimes referred to as “vehicle interface adapter”) are an electronic device that allows a computer to access the vehicle network. It is similar in operation to a computer modem, in that it translates messages from one protocol to another.
Choose an off-the-shelf adapter to get the best price and the shortest time-to-market. They come with a variety of connection options, support all legislated OBD-II protocols, and free lifetime firmware upgrades.
