Hi,
I just bought an Arduino MEGA 2560 Rev3 from robotshop but it is running very hot. Even when running the simple “blink” program (turns a diode on and off) and powered by USB, the microcontroller chip quickly becomes burning hot. No other components, including the voltage regulator, warm up.
I have used Arduino UNOs before and never had this problem. Is it normal for the chip to run hot on the MEGA 2560 or is mine defective? Thanks!
Cheers,
Thomas
