About DC-DC, Step down “buck” converter pins
1 – Input “+”
2 – Input “-” (GND)
3 – Output “+”
4 – Output “-” (GND)
5 – Output voltage adjustment
6 – Current limiter (due to the specifics of DC-DC modules, we do not use it)
Voltmeter and ammeter
The voltmeter and ammeter measure the real voltage and current consumption by the laser module.
This gives a picture of the power intensity and laser power.
The temperature sensor is added to the laser heat-sink and measures temperature of the outside the laser heat-sink.
The temperature outside the laser diode on a heat sink should not be more than 55-60C (140F max)
Power supply 3V (2 batteries 1.5V type G13 / LR44 / 357)
Measuring range -50 – 110 degrees
The Arduino board is used to setup laser power remotely (duty ratio/frequency).
Connect the Arduino board and change laser power parameters.

Endurance MO1 PCB
Endurance MO1 PCB is needed to use Arduino board.
Input voltmeter (optional)
Input voltmeter measures input voltage.
Input current gives a picture that is the power supply is enough for the laser. If the voltage drops then the power supply is not good enough.
