  1. Hello

    Can I ask about the connection of the DQ542MA?
    I collect a DLP printer.
    I want to connect the Raspberry to the straight line with the DQ542MA like your circuit.
    GIPO Raspberry 3.3 V in Control At the input of the DQ542MA need 5 V
    Is there enough 3.3 V in for driver management?

    1. Hello,
      I have not had any problems running the DQ542MA drivers with the signals directly from the PI on my simple bench test setup shown in the video. However a logic level converter (3.3v – 5v) could also be added to the setup at little extra cost.
