I'm trying to locate something for a customer to connect to one of our SBC's.
Why can't I find an inexpensive operator interface? You know, something like a mini-terminal with RS-232.
A squared away design where you can cut out a rectangiular hole and drill 4 mounting holes and put it on a panel inside a NEMA box or something. Not pretty, but inexpensive and useful.
(Not some PIC project, I have found most of them. I have also found all the so called inexpensive PLC oriented ones for $500. Not those either.)
