SBC GPIO Single Fan Controller (software)

This is the fan controller circuit built for my Orange Pi 5. This tiny board can be plugged directly on Pi 5's GPIO. It used 3 pins and hide another 3 pins. It takes digital state of a GPIO pin to turn on/off a single fan. I don't have experience in board design so the components may be out of the way, but the looks exactly like what I designed, and work exactly like what I expected it to. The components looks a bit suspicious (I mean look at the print on those components), but they work so I have no complain. Overall, very good first experience on PCBWay.
