Description: This board allows you to interface with your car’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.
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.
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’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.
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.

This interface works like a charm, it accepts all ELM327 commands with no problems. Interfacing it with the serial port of Arduino it’s easy. One of the best products of SparkFun IMHO.
Nice to have: the same card (optionally) without the DB9 connector. I would prefer to solder the wires directly on the PCB. In fact, the connector grabs a lot of vertical space in your enclosure box.

This board does all it’s asked to do. I haven’t had any problems. The only reason it’s not 5 stars is the warnings I have when using the ELM attachment to disconnect the UART when I flash my Photon or the flash operation can inadvertently “brick” the UART. Really? If that’s wrong, I’d love it to be refuted - save me some time and trouble.
Works like charm, easy to hook up
