  • after working a bit with the UART, both RX and TX LEDs are lit continuously and I cannot get any response from it. I guess my board is gone, I wonder what should I do to avoid this situation with the next OBD-II UART board I buy?

    You'll also need a way to power the Arduino while it's in your vehicle since power can't be taken from the OBD-II-UART board

    The VBATT pin on the board is connected to the OBD-II VBATT, i.e. to the car battery. Is there any problem with taking power from there to my Arduino application? It's not the OBD-II UART giving power, but the car itself...

No public wish lists :(
