    @vladimir capacitors are only to smooth the DC supply. A 0.1uF and 10uF is what I just normally whack in there... But check the datasheet for the 5v voltage regulator you are using for recommendations. (LM2940CT = 0,47uF Input, 22uF Output)

    Resistors are optional and depend on if the gate needs some current limitations on the mosfet. If you are using the recommended mosfet you can just bridge these with wires. If not...check datasheet. (Does mostefs ever needs current limitations?)

    @sundberg84 Thank you for the clarification! Can you explain to me why you use a combination of 0.1 uF and 10 uF, instead of the recommended 0.47 uF and 22 uF?

      @vladimir because in lazy and sometimes doesn't check the datasheet. These values comes from the LE33 voltage regulator...

          @sundberg84 Is there a sketch for this device? Where can I find it?

            @sundberg84 And ... I do not use Easy/Newbie PCB. Will there be enough voltage at the conclusions of Arduino Pro Mini 3.3V for tape management?
            I now experimented and accidentally burned the voltage regulator in Arduino Pro Mini 3.3V, applying 12 V to the RAW contact.:man-shrugging:

              @vladimir at the moment I do not have a sketch but there are plenty on the forum (Like this).

              There will be more than enough current to run the normal Mysensors node.
              If you use the recommended LM2940CT you will have about 5 times more than needed.

                @sundberg84 The connected LED strip lights up, but for some reason the Atmega chip is heated very quickly and strongly. Have you encountered this?

                    Do you plan an RGBW version?

                      @yoshida I'm not sure... Maybe 😉
