new to all this but great fun. I have a raspberry pi3 and i did have a fan connected to it. I just added a power supply battery. i also added a IR remote and power button which sits onto of the gpio pins. So now I have no Pins that i can plug my fan into. what does everyone else do?
thanks
This is the uri of it as away from desk https://www.robotshop.com/media/catalog/product/cache/image/240x240/9df78eab33525d08d6e5fb8d27136e95/i/r/ir-remote-power-module-raspberry-pi_1.jpg
The hat you are using is not taking all GPIO ports, see bottom of the board:
Use of any of remaining GPIOs. Soldering would be required.
Do not forget that if you want to drive a fan which needs more than 15mA (most of fans will take more) of current and more than 3.3V of voltage supply you would need some sort of transistor switch or relay (again, driven by transistor). Check this link for current limitations.
See this link to see how to drive motor with RPi and transistor.
---EDIT---
If soldering brings too much hassle, you can try breadboard and Raspberry Pi GPIO to breadboard interface. Picture from below show seedstudio's kit.
Amazon sells similar item under name of 'Raspberry Pi GPIO Breakout Board Bundle', or something like 'T Type GPIO Breakout board for Raspberry Pi' It gives you basic set with jumper leads to connect whatever you need.
When you proof your set is working, you can try to mount it on protoboard (soldering required!).
