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+.
