Hello X and other builders. I am having a brain teaser with the dual rail SLB. Not with the actual schematics or layout, but with these 2 little helper boards I have purchased.

I would like to use a 4 pin molex box adapter with these blue helper boards.

Could some one tell me what the numeral 1 on the blue boards signifies ?

Am I correct in thinking that the molex box on the blue boards should be C-C-E-B starting from the upper left corner of the box proceeding clockwise ?.

I am also attaching a pic of the bottom of each of the blue heiper boards to hopefully explain my thinking about the molex pins.

Thanks a lot for the help.

Use your DMM to. confirm, but just by looking at the traces, it seems to signify the pad corresponding to pin 1.

Thanks IAIMH,

So for the N-BJT board using BCE: In the molex box 1 is B. Proceeding CW from 1 it is E, E, C

So for the P-BJT board using BCE: In the molex box 1 is B. Proceeding CW from 1 it is C, C, E

I don't know why the difference, but will be aware when running wires from the molex box to the SLB.

Thanks for the hint.
