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
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
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
Endurance power generator sketch
Arduino generator for the laser (power and period)
Endurance MO1 PCB
Endurance MO1 PCB is needed to use Arduino board.
Size 50x23x5mm
Weight 6g
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
