Hi,
I've decided to make my own ODBII data loger for my car based on http://www.arduinodev.com/hardware/obd-kit/. But I'm stuck with question can I power up arduino directly from ODBII? Or should I make seperate wire connection with 12V current (for example from car lighter).

I usle ODB2 interface with ELM327, on output I've already have Tx,Rx signals.

Br,
Marcin

You can take power from pin 16 of the ODBII connector, that's what it's there for.
