I have an ATMEGA2560 Arduino board which is sinking 75 mA. It seems to me it's unreasonably high. I check ed the datasheet of ATMEGA2560 micro and it shows a 20mA at 16MHZ clock. There's in addition the bootloader serial microcontroller which I assume to be sinking other 20mA. There's still 35 mA…

ATMEGA2560 current sink ?
