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
    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.

     

  • Temperature sensor
    Temperature sensor

    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)

    Size 45x26x16mm
    Weight 15g
    Power supply 3V (2 batteries 1.5V type G13 / LR44 / 357)
    Measuring range -50 – 110 degrees

  • Arduino board
    Arduino board

    The Arduino board is used to setup laser power remotely (duty ratio/frequency).
    Connect the Arduino board and change laser power parameters.

    Arduino Nano:
    Size 44x18x15mm
    Weight 5g

    Arduino generator for the laser (power and period)

  • Endurance MO1 PCB
    Endurance MO1 PCB

    Endurance MO1 PCB is needed to use Arduino board.

    Size 50x23x5mm
    Weight 6g

  • Input voltmeter (optional)
    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.

    Size 45x26x22mm Weight 14g
    Power supply 4-30V
    Measuring range 0-100V, 0-10A

  • 2 buttons switch
