My connector wired holes do not look like any of these standards you posted, neither 9141-2.
As far as I know it uses iso 9141 standard.
So none obduino is for older 9141 and therefore I have to try to implement mpguino?
I am looking to build my own OBDuino. However, I am running into parts availability issues. I am looking for a replacement for the Si9241A / SI9243 chip. The originally used MC33290 is long since obsolete, and it seems the Si9241A and SI9243 are now also obsolete. Does anyone know of another valid replacement?
