Arduino Nano classic - power support for OLED and buzzer

Projects General Guidance

Hi,

I find different information for the classic nano for the output power at 5V pin.

I like to add an OLED (20ma) and a buzzer (40ma). The overall consumption should be round about 100ma max for external components with an input voltage of 12V. Could the internal supply handle this or will it die at the end? From the specs of the IC it seems fine.

Thanks,
Nils

What do the specs for the regulator tell you about not having a significant heat sink? :roll_eyes:
