Description
PCB layout is designed for laser diodes with N-Type connection.
The power adjustment of the laser diodes is carried out with the
R2+R3 resistor, which is parallel to the already equipped R1 resistor.
R1 has a value of 36 KiloOhm, so that most laser diodes can be
operated in lower performance range.
In order to increase the optical power of the laser diode, the total
R1//R2//R3 resistor is decreased by the R2+R3 resistor.
