      I have a Duet WiFi and a Duex5. For a coming project I'm planning to use the unused fan pins for water cooling and to power some led strips. My question is: what is the max current the fan pins can deliver ? The water cooling will need 0.6 A and the led strips 0.4 A

        Those currents are no problem, however if the water cooling uses a brushed DC motor then you must connect a flyback diode in parallel with it. The version 1.02 boards when they arrive will not need the flyback diode.

        Maximum recommended continuous current for the controlled fan outputs is 1.5A each.
