      I'd like to ask if it is possible to connect a pwm mosfet module to a free heater pin on the expansion connector for controlling more fans?
      The pwm module looks like this and it is for 3.3VDC input:

      Do i need some "special wiring" like a fuse or diode somewhere to protect the duet?

        @cosmowave If anything, I'd look for an optocoupled PWM board, but IMHO it's unlikely that a dead MOSFet backfires through the gate and damage the duet.
