Good day Sarma
Yes it's old now . OP has probably taken off
Its interesting though . I regularly put 12 Volt on my Arduinos because its usually convenient using a 12 Volt battery . They don't run out so quickly if you use a car battery.
Am I right in concluding then that ,even at 24V, if you reduce the current draw by say interrupt code and short run times, with long shut down periods to allow cooling, you could get away with it? Or even adding a heat sink to the on board regulator
The trouble with fools is that they do not realise their foolishness.
These forum sitters you have here are a pain . They don't try to help really . What they do is jump in and confuse the thread.
You don't know anything about a situation unless you have experienced it specifically yourself ! Period
I suggest you stop wasting peoples time who come here for an answer.
Leave the answer to someone who does know.
In my case the answer was simple but I found it on a more sensible forum -not this circus
