Hi Vitaliy,

That does look interesting - I am curious, though: I guess ScanTool
LLC is the same company as OBD Solutions? Do you also license the
firmware instead of just selling pre-programmed ICs? I ask only as a
curiosity - I am somewhat interested in the chip as a hobbyist but I
don't work in the automotive field so I am not in a position to want
licensed firmware.
