I have a V3 MS and am working on building the daughter board. Since I have the 1st VR sensor on the MS. Do I need to use VR sensor 1 or 2 on the daughter board. The latout only shows connections for the V3 on sensor 2. I already built sensor circuit 1 though not noticing the difference. Is this an issue? Also I noticed that the circuit 1 has a different R4 value than on circuit 2 which makes think they are different. Any thoughts?

Thanks

 

If it's the same LM1815 circuits as the error* V1 board,then circuit 2 is the 2 tooth one(the one with the 82K resistor).
