Thank you - that's useful. I see you broke up the thermal pad with the solder mask, which is as recommended. Do you know how to do that with kicad? I tried creating a zone on the mask layer, but it didn't work. I've therefore gone for creating an array of dummy pins (ie 33 onwards), all

Hi, I do not know this footprint, but when I need a zone in the midle of a footprint, I also create a row of square pins all of them with number 0 (zero). So I have only one pin with number 0 in the Eeschema component. If you create a single big pad or a zone in the module, the component wil

I assume you are refering to the drawing 32M1-A on page 355 of the That's the one. datasheet? Why did you choose this package when a 28 pin DIP and a TQFP seems to be an option. Because the other two packages are much bigger, and this one fits the available space :). Regards, Robert.
