I'm looking to attach a 5v fan to my FFC-3P and I know it has the fan header for power, I was wondering if there are any GPIO pins available for fan control though? I know I can get the chip temperature through the API, if there is a GPIO pin I could send PWM to though that'd be ideal.
If not, there are loads of ways to do this, I just thought this may be an easy win if so.
Hi edxian , kneave ,
Usually, a fan wouldn't be needed, and passive cooling suffices. For GPIOs, you can check schematics to determine best (most convenient) pin to use : https://github.com/luxonis/depthai-hardware/tree/master/DM1090FFC_DepthAI_USB3
Thanks Erik, is usage of the GPIO included in the SDK or API please?
edxian I'm not sure of the temperature at the minute to be honest but noticed it getting warm when I was only previewing video and thought it worth planning ahead. Mine is in an enclosure with a fan at the back and two vents the other side of the 3P board, I'm expecting air passing it will be enough from the size of the heatsink so haven't looked at putting a fan on it directly.
Hi kneave

Also, yes, the device is going to get warm (hot even) but it should cause any problems unless there is a hardware issue with something like the thermal paste. Most likely that is not the case and passive cooling is enough.
Hope this helps,

Amazing, thanks Jaka!
