OBD-II UART (CAN) Vehicle Identification Kit

This is a kit includes, OBDII - UART converter module and DB9 converter cable neededfor connection. You can read sensor data, detect fault codes and acces various information from your vehicle via OBD port.

You may see the Wikipedia page for detailed information about OBD system.

This board supports common used communication protocols like CAN-BUS and JBUS with its ELM327 supported STN1110 chip. You can find UART communication pins on the board to connect Bluetooth or FTDI modules. OBD-DB9 connection cable is not included in the product. To use it via a computer, you need an FTDI cable or a similar USB-UART converter.
