mana board to low pwm voltage



  • Hi,
    my eleksmaker mana board v2.1 only gives 0.59 volts output for the laser pwm (on S & -) , this should be 5 volts to put the laser on full, 0.59 volts it's not even enough to put 'weak' on.
    I have tested the pwm input on the laser (2300mw) with a input ranging from 0 to 5 volts, and the laser is working properly, it starts to light up around 1 volt, and at 5 volts it's on full power.
    The power supply to the board is 12 volts 5a and everything else on the board seems to work properly....

    Best regards,Rik
