We have realeased a DIY kit to build your existing PreenFM into Eurorack module.
Its a full kit. You will have all the parts you need to do it.
Due to differences in some version some extra steps and parts might be needed to complete the mod.

Hello

I received a preenfm2 eurorack retrofit diy kit

Do you have a diagram of the electronic board?

For example, i do not know the position of the diodes

Thank you

Best regards

Pictures from Van Daal web
Thanks to Ardi Mäesalu
Excellent!!




D10-D13 are 1N4XXXX
The rest 8 are Schotkey.
 So 4 diodes in the PSU section or Upper section of the board are 1N4XXX.

L1 can be replaced with wire. It might need an inductor if you have very noisy 5V supply in your eurorack.
But its not mandatory.

USB + and - should be wired to the PReenFM main board. There is a connector labeled USB 2- 3+.

Hello,
I have now also bought the conversion kit and am still very disappointed.
I have the following questions:
Which software version is needed and where can I get it?
Is there a reasonable construction manual for the modification?
What about the IC3 7805? Do I have to solder it in?
Where is the circuit diagram?

I'm really in doubt whether I'm going to do the modification.
The information is nevertheless very daring.
Has a user of the Preem already done the modification?

Greetings Klaus

What is your disapointment about?

You need to poulate the boards and wire it together and your are ready to go.
I will answer all your questions by email.

Firmware is available on PreenFM Github.
https://github.com/Ixox/preenfm2/releases
Get this file: pfm2_Eurorack_2.09a.zip


The modification has been done by many users.

Another step on the way.
A dedicated PCB for Semimodular/Eurorack design.
The depth of this module is 3cm. Which makes it Skiff ready.
A special Skiff is in developement. That will allow to use USB to power the system.

Ok,
have build it.
The firmware version P2_209AO.BIN cannot be used with the rebuild,
the modification is not implemented.
Version P2_209A.BIN has this implementation. So you can't use the overclocked version.
Otherwise the rebuild worked and it would be nice if the version P2_209AO.BIN is supplemented with the CV.
Hope that I'm right.

Greetings
Klaus

Can be a mistake when building the zip file.

Very odd.

I just downloaded the file again and installed it: and behold, everything is fine. Somebody should understand that.
Now all I have to do is figure out how to get a preset of a sound by turning it on.
