  • You Reply: Please add to the FAQ the following questions, and you can safe erase my post after:

    1. Your chipset used for CAN comunication is compatible or produced by the ELM company?
    1.1 In case of a positive answer, does this have support for all the commands described in the datasheet?
    1.2 What version (regarding the ELM compatibility) has the chip?
    2. Did you ever tried to measure the current consumed by your device ? In the ELM datasheet is an example that consumes less than 1mA. Also, what power saving functionalities has your chipset, and what is the current used in idle (in the latest version of the A model, where there is mentioned an improvement of the DC power supply)?
    3. The devices outputs current to the arduino even when the engine is off? Let's assume that the OBD has power when the engine is off.
    4. Can you comunicate via CAN when the engine is off ? Let's assume that the CAN-LO is on and you can cumunicate with other devices. Can this be possible with the Arduino OBD too?
    5. It would be nice to have some photos with the device opened, so we can examinate the board connections.


    Beside that, I would see as an improvement: In the ELM datasheet is the pin 16 which can be used for power-saving functionalities. I think that for some users (like me), it would be useful to have that pin as an output too.

    Thanks in advance :)
