A user posted this question on Stack Overflow. I close-voted and left a comment that it felt like an electronics question. They then posted the question to SuperUser.
I asked them why they didn't post it on Electronics, which was met with:
The questions I´ve looked at have nothing to do with my question, or does not answer it in a manner I understand (ie software developer perspective).
Before I push for them to post to Electronics another time, I thought I'd verify that the question is on-topic and answerable. Should I continue recommending that the OP posts it here?
(Edit: if you think that it IS a software question, please let me know that too, and I'll be happy join in a re-open vote.)
