Clouds is my 7th DIY clone of a Mutable Instruments module. I am sharing some details about how I built the module. That included the scary part of soldering a QFN chip, which turned out not to be problematic at all.
I also show the programming process for the microcontroller.

Again, for anyone who also wants to build the module, I created another GitHub repository with all details:
