Compliments Gambatte, I hope that it will work on my Guzzi Stelvio too.
Somabody knows if it is (somehow) possible to connect a simple (waterproof) 1-digit led display to the OBD adapter? As I see there is only a 2 pin line that can be used...
With arduino I can do it easily by driving every segment of the display, but no idea on how to do that with the OBD2-UART adapter.

Hello,Stanley,
like stated 2 Posts above:
i have got your OBD II Adapter for Arduino,Type B.
Could you please take a look at the picture included in the post above,if pin7 is supported (this is used for KWP2000 and CAN via K-Line) ????
Meanwhile I have opened the Adapter, and i see, that PIN7 has no connection.
Could you please check this, and give some Information?
Thank you very much!

Pin 7 is used by KWP2000.

OK,Stanley,thanks.
But: My Bike uses KWP2000, and it does not work.
The Issue seems to be,that inside your Adapter PIN7 has no connection.
Best Regards

I can confirm you that pin 7 is connected and used.
