Add a Chassis Fan for Bolt?

Dear all,

If I want to add a Chassis Fan for Bolt,
Am I right that I should connect a 5V Fan (50x50x10mm) to CN25?
* CN25 (MicoChip MEC1705, 3.3V embedded controller pinout)
# pin11: FAN_OUT0 -- 5V? or just 3.3V?
# pin12: FAN_TACH0
# pin29: GND
-- according to https://www.udoo.org/docs-bolt/Hardware_References/Pinout_Headers.html

I have the following questions too:
(a) Is pin11: FAN_OUT0 5V?
(b) how to download the program to the microcontroller MEC1705?

Thanks for any kinds of help!

 

This is what is written in the PDF hardware user manual.

 

On the X86 the fan controller is updated by Udoo UEFI (BIOS) updates.

 

pls. noted that
This is about the CPU Fan connector!

However, I am looking for the way to add an additional Fan for overall cooling of the whole chassis
-> so any Udooer know the proper way to do so?

Thanks!

 

FANOUT_0 is a logic level output, which needs a motor driver to make it work.
(Don't recall it is 1.8V or 3.3V logic level... however, need a driver anyway.)

MEC1705 is a critical component of the system operation. Leave it to factory to deal with it.

 

what motor driver which Udoo Bolt is using to drive the CPU Fan?

and where can I download the schematics of Udoo Bolt?

Thanks!

 

Should appear on this page soon https://www.udoo.org/docs-bolt/Hardware_References/Resources.html

@evaloverde ETA?

 

Would be nice to know if the CN25 fan pins are connected to the on board fan or if they are available for a second fan?

 

It's for a separate fan. Need a motor driver though.

 

No!

The link does NOT contains any helpful information about motor driver and schematics!

 

I know but it should so I asked Eva of the Udoo team when it will be placed there.

 

Thanks!
Hope they will there soon!
