NanoPI T4 3-pin fan with PWM suggestion needed.
I'm about to install active cooling fan on my recently delivered nanoPI T4. However, I cannot get what is a type of the soldered 3-pin fan connector on this board? What I see there is visually too small as for standard connector size. Is it something special I have no clue about yet, or it is for future proprietary Friendlyarm's fan designed specially for the board?
Any suggestions are welcome!
Thanks
It should be tough to ignore, given that it's monkeying with the duty cycle of the fan's power input. Do you have a way to measure it?
Hm... I've never measured a PWM signal with a multimeter - I've always either just plugged into a PWM-capable board or wired up a voltage divider (mostly just a pot -> ground, as the fan has a voltage source if it runs with the PWM disconnected). Beyond playing with the little resistor pigtails that come with various PC fans, I've never tried to control f
