My "Ultimate" 3A+ Build - With Temp-Controlled Fan

[infinitLoop]

I also opted for digital controls, so that I could use this Nav Toggle as a hotkey for the battery monitor and shutdown.

I was wondering could I just hook up the nav toggle as a regular button to the gpio and use it as volume up and down with retro arch.
Also amazing work I am using you fan vent for my build

thanks

sure, it's basically just three buttons in one, so you can use it however you can use digital buttons. just connect the three pads from it to three gpio pins, along with the ground connection from/to it, and then adjust your script or whatever for those pins.

Great project and result Sir!

I really want to copy your fan approach, just not sure if it can be done on my setup. I am planning on using a DPI screen with Tinkerboy's dpi adapter (which occupies all GPIO pins) but since pins are available from the upper side of the 3b+, can I solder the fan's wires there? Is the transistor mandatory?

yeah, i think you should be able to use those pins that are free on the dpi adapter, if they aren't taken up by anything else. the transistor is what handles the switching on and off, so if you want to have the software control it you would need that. you could just put a fan in that is always on too, and not hook up anything to the pi.

Great info, thank you!

I am waiting for the SUNON UB5U3 (plus all the rest parts) and will probably go for your solution. Thank you for the transistor clarification, it's nice to know the purpose of each part.

Cheers!

Thats one awesome built you did! Great job
