I have noticed whenever I use an external power adapter to power the arduino it gets hot. It is a 12V 1A adapter. I put my finger on the AMS 1117 (component next to the barrel connector) and I feel it gets very hot.
I’m using an Arduino Mega2560.
Is this normal? if not, how can I fix this problem?
Thanks in advance
