    Good day!

    I am Peter From Slovakia!
    I now buy the QSFB3. I have DIY laser projector. I have problem with Red laser modulation. If i connect the FB3 to PC and Projector to FB3, Blue and Green laser is no lighting , only Red laser. If I make lasershow. green and blue is modulate, but red only light all time. GND is the same of all laser driver.. I think it be GND probleme.
    I have in ILDA used pins: 1, 2, 5, 6, 7, 14, 15, 18, 19, 20, 25

    I fixed the problem!
    Now I have LPC diode.I think the diode was Ground from heatsink. I took the module from the heatsink, probleme is fixed! I need electrically insulated the heatsink! I think I buy other diode with other pinout, is be good, because pinout is other. :sillylol:

    I am happy now! Software and DAC is perfect! Respect!

    If I finished my DIY projector I upload photos! :)
