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. 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.

此板允許您與您的汽車的OBD-II總線接口。它為您提供使用ELM327命令集串行接口，並支持所有主要的OBD-II標準，如CAN和JBUS。該主板還提供了直接隊友我們FTDI Basic或藍牙伴侶足跡。與我們的DB9到OBD-II電纜DB9連接器配合如下。
車載診斷系統，第二代（OBD-II）是一組用於實現基於計算機的系統來控制車輛廢氣排放標準。這是首次在美國推出於1994年，並成為所有1996年和更新車輛美國的要求。其他國家，包括加拿大，歐盟的部分地區，日本，澳大利亞和巴西採取類似的立法。現代車隊的大部分支持OBD-II或其區域風味之一。
除其他事項外，OBD-II要求每個符合車輛配備一個標準診斷連接器（DLC），它描述了與車輛的計算機，也被稱為ECU（電子控制單元）通信的標準方法。豐富的信息可以通過點擊進入OBD總線，包括故障指示燈（MIL），診斷故障碼（故障碼），檢查和維護（I / M）信息的狀態，凍結幀獲得，VIN，數百實時參數，等等。
STN1110是一個OBD到可用於當前使用的任何的OBD-II的協議之間對信息進行轉換，和UART的UART解釋器。它與事實上的工業標準ELM327指令集完全兼容。基於16位處理器核心，STN1110提供更多的功能，比任何其他ELM327兼容的IC性能更好。
特徵：
- 與ELM327 AT指令集完全兼容
- ST擴展指令集
