Re: [Xylo-SDR] Questions - Enclosure - MB - Kicad
So far the ONLY non Digi-Key off the shelf part I am suggesting is the
enclosure. It meets both horizontal and vertical EuroBus standards.

I am with Lyle. PLEASE let's adopt standard connectors and controls
that are available from standard sources in small quantities and mounted
on the circuit board! I don't need a full kit. What I need is to not
have to figure, scrounge, drill, saw, poke, curse, ... I just don't
have time and I am trying to quit (the latter).
