In this schematic link's you've put some values are unknown.for example R15,R8,R6 .the exact amount of lead resistance harrow say?

Hey,

R8 is 33k.

R6 and R8 are not placed because they are optional. R6 might be put if you want to skip transistor T2. R8 might be put if you want extra protection on the T2 during powering events (it should probably be 510k or more).

Resistors which have value "NA" are not placed on the board by default. "NA" stands for "Not Assembled".

Please refer to this forum thread on why some resistors are NA and why we place resistors 0(zero) Ohms: https://www.olimex.com/forum/index.php?topic=2375.0
