Hi, im looking for way to programmatically switch small 5VDC 0.08A fan ON or OFF with Nano v3.0 board. No speed control needed. What would be a best and novice friendly way to do that? Mosfet switch module feels like a "too much", maybe.

At only 80ma, a Low side switch (NPN BJT) or High side (PNP BJT) switch can be used.

Do you have an external 5V power supply ?

thanks,
yes, i have a external 2A 5VDC power supply for nano board and wanted to power fan from same supply
If the fan has a PWM control pin, you can use it only for start/stop.
I have a lot of small fans and all of them has only 3 pin (without PWM). But found small 4 pin 5VDC fan in online shop, will order and try it out. Thanks!
