Description

The hardware board is an OBD to UART interpreter hardware board that provides bi-directional, half-duplex communication with the vehicle’s On-Board Diagnostic system (OBD-II).
It supports all legislated OBD-II protocols.

A wealth of information can be obtained by tapping into the OBD bus, including the status of the malfunction indicator light (MIL), diagnostic trouble codes (DTCs),
inspection and maintenance (I/M) information, freeze frames, VIN, hundreds of real-time parameters, and more.

The hardware board features the STN2100. It is fully compatible with the de facto industry standard ELM327 command set.
Based on a 16-bit processor core, the STN2100 offers more features and better performance than any other ELM327 compatible IC.

On-Board Diagnostics, or OBD, is a computer-based system built into all 1996 and later light-duty vehicles and trucks, as required by the Clean Air Act Amendments of 1990.
OBD systems are designed to monitor the performance of some of an engine’s major components including those responsible for controlling emissions.

OBD is the language of the Engine Control Unit (ECU), and it was designed to help fight emissions and engine failures.
You can determine what the Malfunction Indicator Light (MIL)(aka the Check Engine Light) on your dash is referring to when it tells you there is an engine problem.
If you or your mechanic has ever read the DTCs (Diagnostic Trouble Codes) on your vehicle, they are using OBD-I
