  7. &lt;strong&gt;Description:&lt;/strong&gt; This board allows you to interface with your car&amp;#39;s OBD-II bus. It provides you a serial interface using the ELM327 command set and supports all major OBD-II standards such as CAN and JBUS. The board also provides a footprint which mates directly to our FTDI Basic or a Bluetooth Mate. The DB9 connector mates with our DB9 to OBD-II cable listed below.&lt;/p&gt;
  8. &lt;p&gt;
  9. On-Board Diagnostics, Second Generation (OBD-II) is a set of standards for implementing a computer based system to control emissions from vehicles. It was first introduced in the United States in 1994, and became a requirement on all 1996 and newer US vehicles. Other countries, including Canada, parts of the European Union, Japan, Australia, and Brazil adopted similar legislation. A large portion of the modern vehicle fleet supports OBD-II or one of its regional flavors.&lt;/p&gt;
  10. &lt;p&gt;
  11. Among other things, OBD-II requires that each compliant vehicle be equipped with a standard diagnostic connector (DLC) and describes a standard way of communicating with the vehicle&amp;rsquo;s computer, also known as the ECU (Electronic Control Unit). 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.&lt;/p&gt;
  12. &lt;p&gt;
  13. STN1110 is an OBD to UART interpreter that can be used to convert messages between any of the OBD-II protocols currently in use, and UART. It is fully compatible with the de facto industry standard ELM327 command set. Based on a 16-bit processor core, the STN1110 offers more features and better performance than any other ELM327 compatible IC.&lt;/p&gt;
  14. &lt;p&gt;
  15. &lt;strong&gt;Features:&lt;/strong&gt;&lt;/p&gt;
  16. &lt;ul&gt;

  41. Support for non-legislated OBD protocols:
  42. &lt;ul&gt;
  43. &lt;li&gt;
  44. ISO 15765&lt;/li&gt;
  45. &lt;li&gt;
