BTW what pins do you use to power the fan?

here is my setup, i've posted earlier but who likes to read previous posts? ;)

actually my heatsink is 28x28 and it's too big. Some surrounding components are higher than FPGA chip, so i had to make a
notch for near capacitor (as you can see in pic).
My measurements show that perfect size of heatsink would be 25x25. You can use smaller heatsink but it won't cover a whole chip. Anyway 22x22 or 23x23 should be fine.

If you don't have I/O board, there is another place of +5V source: you can see the brown wire going from USB connector to a small connector near ethernet: +5V - PIN1, GND - PIN10

Why not simply use the 5v supplied by the Arduino connector ?

Another way to make fan more silent is to use 12V fan connected to 9V on arduino or LTC connector.

why you think 5V on arduino is simpler than 5V on 10pin ADC connecor?

I assume that Arduino boards are not always of strong quality and that the nano board must have some kind of protection, moreover they could harness some power.

I guess (after the initial comment) you finally got it :)
I could also say you don't read previous posts, where are stated on several occasions I don't have, and don't plan to use the I/O board... You see now, I hope, it doesn't sound really nice... But ok, no offense taken, really :) So the real question was related to the Nano board actual 5v source regardless the "upgrades" and considering you are familiar with the board, knowing there might be several options.

I believe I have tried to be constructive on the thread, and an early adopter, with unfortunately not much time to deal with it.

Appreciate your work, I hope MiSTer will only grow.

If you're not using both or only one daughter board, this might help getting 5v for a fan.

The Arduino headers pinout if you'd rather use those.

I hope this helps some people.

Stupid question on the side, but the SOC should have an internal temperature sensor, which can be read from the ARM?

This is from PDF file which you can download from Terasic site from resource section, DE10-nano User Manual. All connector descriptions and pin-outs are there.

Yes, usually this kind of information is there...
Since the sole purpose of buying the board was/is MiSTer, I was hoping I would not be reading the manual for the dev-board. Obviously I was wrong. Thx anyway.

Cyclone V has no thermal diode. Only upper level chips (Arria and Stratix have them). https://lists.rocketboards.org/pipermai ... 02172.html

It's not an user-oriented product. It's really a DEVELOPMENT environment both from hardware and software sides=) Enthusiasts can use it for fun, but no one cares right now to make it commercial grade usability.

Guess, I'm a spoiled xilinx user. But seriously, how do they adapt the DDR timing to the envieronment, if they don't measure the temperature?

I am quite aware of that, and I am a developer myself with 30+ years of experience. This project is for me at the moment for fun, having very limited time to spend even for that right now.
Who said anything about "commercial grade" usability? I have managed to make my way using the information on Github including making myself the memory board (reported the results here), so I think it says enough.
I just wanted a simple info - which pins (by experience) would be recommended to hook up the fan. I guess this is what the forum is for - sharing knowledge in order to help other people not necessarily going the
full trial and error path. (or reading the documentation which might not necessarily give the definitive answer and is not directly related to what you actually want to do. I would understand if there was a dedicated fan header, sure)
Also you should make a distinction - it is not the same to develop for the MiSTer and using DE10-Nano as a general purpose dev-board. In the first case, I would read the MiSTer docs/manuals, and in the second - DE10-Nano manuals. To be honest I never even booted the Nano using the originally provided SD card... First boot was with MiSTer.

I hope I will see more helpers in this project. I don't mean exactly developers. Advanced users also can help to project by adding some usage info/hints. I can give WiKi access if some one is willing to help.

I'm quite busy by this project but cannot provide everything quickly. I know, most of users want just all info ASAP without realizing that I'm not a company but single person who doing this for fun.

This project is not about one person providing the whole hardware, whole software, whole documentation and others just need to wait for spoon feeding. It's not!

Don't ask "what else Sorgelig can provide to me?"
Ask "How can i help the project?"

I had already asked the same for the Mist-Board, without success.
My English is to bad for Wiki and i have no Plan about Linux.
The only thing I can help is the porting of cores (which then but still require rework).

Thank you for your fantastic work

Mounted 5V Sunon maglev fan from some laptop (it has own heatsink) and powered it from 3.3V (arduino header)
It works, but I'm not happy with level of noise it produces. Probably will try dc-dc buck converter to power it from lower voltage.
But as for heat dissipation - works just fine

:megaphone: UPDATE: mpattom just added 9 IO Boards to the Buy / Sell MiSTer Expansion Boards Thread!!!


--- Old Message ---

I had some people asking me for another batch of IO Boards and decided that I would do another round if enough people are willing to do a prepayment. By that, I can buy the components without the financial burden. I would sell the remaining boards again in the MiSTer Buy /Sell Thread

I am asking around to put people on my waiting list. Assembly takes me about 3-4 hours per board, therefore, I take 30€ + 6,20€ shipping cost. I'm gonna make a mailing list and keep everyone updated through the whole process. It will be the actual IO Board version with the sturdy VGA connector but without optical fiber connector (except you are willing to pay for that madly expensive thing :D )

Components and packaging will cost about 200€, so I need at least 7 people on the waiting list. I make personal customization if you would like different LED colors or other connector types.

Just let me know if you are interested via PM or Email


:cheers:

That board looks great. I guess it will rest part of its weight on the Arduino connectors of the right?

It's partly true. Only partly. The board isn't too heavy and 3 original points are more than enough to keep the board with fan.
I've added Arduino part just to accommodate pass through header and be able to add future expansions more easy. I've added +3.3V pins there, so the expansion boards can be more compact.

As I remember there is a standard mechanism for all cores:
- first Enter press on floppy drive item in OSD ejects it
- next Enter press allows to select next floppy image
