Mainly referring to this question: Which voltage regulator should I use? [on hold]
Currently it's put on hold (by me) and has 3 re-open votes from the community so it's obviously worth a discussion to determine what direction the community wants to take this SE in.
The fact that it's an Arduino clone is not relevant to the question. The question is what voltage regulator should I use to get the most out of this battery while still being able to supply X volts and Y current.
When phrased this way, it's obviously off topic. But why does it become on topic if I mention the board I'm trying to power is an Arduino? Take a look at the answers to both Arduino.SE question and the EE.SE question. None of them mention Arduino, at all.
We've had a couple of other discussions regarding other topics but they all have the same theme:
- Are questions about serial communication using third party software on-topic?
- Are questions about IDEs other than the official IDE on-topic?
My policy is this:
Ask "What does this have to do with Arduino?" and if the answer to that question is not significant enough, then the question is probably off topic. https://arduino.meta.stackexchange.com/a/52/11
