I have connected fan (5V, 0.2A) to raspberry pi 3 on pins 2 and 4. When I turn on raspberry, fan doesn't work. Does fan should start with turning on raspberry? Or I have to setup some configuration to get fan working?

  • Power is available on pins 2 and 4 while the Pi is powered. – joan Oct 28 '16 at 8:07
  • @joan PI is powered, but fan doesn't work... – poletn23 Oct 28 '16 at 8:24
  • Doesn't that answer your question? – joan Oct 28 '16 at 8:26
  • I don't know, maybe fan is faulty. Or pins are faulty... – poletn23 Oct 28 '16 at 8:28

According to the official pin diagram, pin 2 and 4 are both 5v.

Try to connect with pin 2 (5v) and pin 6 (ground).

  • Note that many 5V fans work with 3.3V, providing sufficient cooling while making far less noise. So it's worth a try to connect it to pins 1 and 6 as well. – Dmitry Grigoryev Oct 28 '16 at 9:07
  • Thank you @lara-maia. It sounds logical, I have red and black wires on fan. Can I also connect pin 4 and pin 6? – poletn23 Oct 28 '16 at 9:07
  • @poletn23 Yes, pins 2 and 4 are interchangeable, so you can use 4 and 6. – Dmitry Grigoryev Oct 28 '16 at 9:08
  • That's it. It's working on pins 4 and 6. Thank you all. – poletn23 Oct 28 '16 at 16:26
