OBD Reader
General description
One of the supported hardware protocols in the OBD connector is CAN. So it is possible to read out the OBD information when you can send CAN messages. This section shows how you could do this with the E407 and HANcoder.
Hardware
To connect the E407 to the car there is some hardware needed. The E407 doesn't have a CAN transceiver so this has to be mounted externally. For this example we will use the SN65HVD230 but you can use another if you desire. Now we still need a cable between the car and the SN65HVD230. For this there are OBD2 cables available on the internet.
