I started with building MI modules. 603 package size was a little too small for me to begin with.
Sourced the parts to make a full voice of GMSN modules and everything went so well. I’ve built 14 GMSN modules so far and they all work. 805 package size is very comfortable to work with. Using solder paste makes it much more manageable. Rob and everyone on the Slack site answer questions right away. The GMSN site is the best full DIY site I’ve found so far, very impressed!
