That's very helpful Nick, thank you. It seems an odd omission that such information is not in the user manual. I tried to find the Bolt schematics...
Does anyone know the approximate maximum current draw on the 5V_OUT pins on the Arduino interface connector, CN24? I am designing a PCB that needs...
That's interesting and rather surprising but thanks for the information. I searched on all the phrases I could think of without finding the...
Yes, I also checked with an oscilloscope and nada. 510Ω would give an LED current of 10mA, which really should be fine for just about any LED, as,...
Late to this but just now tried connecting my power control circuit to the CN6 header and can confirm that I am not seeing any voltage levels on...
Has anyone managed to find a source for the strange power connector plug, Singatron 45P06CV230-1A00-01? A Google search for that part number only...
I've now updated one of my Udoo Ultras and can confirm that the fan problem is fixed. A few notes to possibly assist others along the way: The...
Hi Tojo, Great, thanks. It's been a long time coming but they got there in the end. I'll have to remind myself how to update the BIOS now - it's...
Can we be clear what has been fixed here? Some were finding that the fan would surge briefly from normal speed to full speed every few seconds...
Tojo says it as it is. I would only add that while a company does not earn money with support, it most certainly does lose money with a lack of...
My situation exactly.
Sad to say it looks like the Udoo guys are busy playing with shiny new things and are not really bothered about supporting their existing products.
Thanks for the information, Tojo. Perhaps the R&D guys will have a sudden epiphany and a new firmware version will emerge.
Sorry to dredge up an old thread but did this strange fan behaviour get any attention?
I don't think this is correct. I am using a three wire fan my ebm-papst, http://uk.rs-online.com/web/p/products/0482106/ and this exhibits exactly...
It comes with bare wire ends so I had to also get the plug shell and pre-wired pins then do a bit of soldering. Not difficult but not a simple...
I use this fan from RS: http://uk.rs-online.com/web/p/products/0482106/ You can hear it at full chat but not at 50%, which is quite fast enough...
The fan on my Ultra does exactly the same thing and it is definitely the PWM controller that is doing it. It doesn't bother me too much as I have...
This approach to cooling the entire board is interesting but I wonder whether it is really necessary. On my Ultra the CPU certainly gets too hot...
Thanks jj. I was coming to the same conclusion. I just happened to have an active cable and thought it might work. Time to get a passive cable I...
