DUO arrived today! The box construction was odd, with spaces that could easily let water, etc. in. I suggest a less “gappy” box for future shipments. I ordered an SWD for programming it; I missed the part that said you would provide it. So… I guess I don’t need two! That will arrive in a few days, then I’ll follow the process. For a first version/prototype, this instrument is beautiful. I’m excited to get into it. I’ll have my 8-year-old and his (same age) friend try it out, too, and try to take some video.
