3.5” Touch UI- how to plug in a fan when display is mounted?

Fri Mar 09, 2018 5:06 am

Hi,

I’m in the process of building a TOUCH UI to go with my CR-10S printer, I have octopi loaded & ready to go, display is mounted & calibrated... Now i’d like to add a 3.5v or 5.5v fan to keep it cool within the case. As i’m Looking into this I realize that the pins where tutorials are telling me to plug it in to, are being occupied by the LCD I currently have installed. Is there any way of going around this besides opting for a USB-based fan? Thanks ahead.

Well we cant see your image as you have not paid photobucket to allow this.

your options for connecting the fan are

1. solder wires directly to the pi PCB or the display PCB

2. use a header spacer like this https://shop.pimoroni.com/products/2x20 ... y-pi-2-b-a so that you can solder wires to the relevant gpio pins

Yes can see your image now and your options remain the same as I said before.

Also I tried to remove the headers from the display but realized these were there:
