I know it's not the tidiest way of doing this conversion but I have looked in this matter extensively and I did find other , more "elegant" solution for the transplant.
Please refer to the following video to see what was my other alternative and the reason I didn't do it.
In the comments of the video you will find technical details about the parts you will need for the alternative transplant solution.
Before I embarked in this journey I did a trial using an Arduino Nano board. After a few trials I was confident enough to do it on my 3D printer to solve a long time issue I had with the reliability of USB Mini connectors.
