I want to run Arduino Mega 2560 outdoor for long time. I found this choices:
1 - 12 V power jack: It makes the board so hot so I skip it.
2 - Vin: It makes the board so hot so I skip it too.
3- 5 V pin: It worked. I heard it makes Arduino unstable because it bypasses the regulator inside it.
How can I solve this? Will 5 V pin work good?
