Rereading the manual pwm control commands, I see that I omitted the command to enable it once you have set the period. [root@pikvm pwm0]# echo 1 > enable

Peter, you didn't say, but the below assumes you are using an RPi4b. With the 4b, you only really have two choices as to which set of PWM outputs to use; GPIO 12&13 or GPIO 18&19 (pi...
Based on the schematics shown, I think the fan contoller you found would work. It's a very similar design to the one I used (perhaps better). Connect the fan to JP2 pins 1 & 2 (minding t...
Note, the kvmd-fan code to fix the PWM mode is on the "pwm_mode" branch of the forked repository linked above.
The 30mm fan that comes with the A3 kit is only a two wire fan, and is connected directly to 5V power. It runs at full speed all the time. However, with a little mod, you can get a PWM ...
