Freematics Forum

Hi all,

I have the Freematics OBD-II Adapter (GPS embeddable) with an analog I/O leadout cable. I was wondering in which arduino pins is these connected and how can read analog data from there.

thanx

It's connected to A4 and A5.

ok, thanks and these are as in arduino with 5Vmax, 10-bit resolution. Correct?
do we have access to Vin to gain in resolution, when sampling smaller voltages?

thanxs

Yes. VIN is not available.
