Arduino Mega current consumption

What is the current consumption of the Arduino mega2560 when supplied with regulated 5V on Vin?

2

You don’t connect regulated 5v to Vin... You can find this in the datasheet for the atmega2560. It’s roughly 80 mA for the chip alone.

3

Is the 80mA indicated in any of the data sheets?

The current consumption of CMOS chips depends on the clock frequency, and yes the datasheets go into
great detail about consumption v. frequency for various sections of the chip and low power modes, since
power budget is a major selling point.

My Mega clone (a Seeeduino Mega, 16MHz) takes about 80 to 90mA, which will be split between the
Mega2560 and the FTDI USB-serial chip.
