Raspberry pi zero w was released on the 5th anniversary of raspberry pi.
Raspberry pi zero w power consumption.
Yesterday my post comparing the raspberry pi zero s power consumption to other pis hit the hacker news front page and commenters there offered a few suggestions that could be used to reduce the power draw even further including disabling hdmi changing the overclock settings and futzing with the lone act led.
Pi hardware raspberry pi zero minimising power consumption disabling the hdmi port make sure you can get ssh access once this is done first so you have the ability to turn it back on again should you need to.
Watts voltage x current so in raw terms the pi zero w at idle will use 0 6w however that ignores any power loss in the psu converting from mains electricity to the 5v needed by the pi zero w.
Assuming 80 efficiency that s still only 0 75 watts which works out as 6 5kwh for a whole year which would cost you roughly 80pence for a whole year in the uk.
This is handy for mobile projects where you re.
The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b.
One of the major benefits of using one of the two models of raspberry pi zero including the new wireless model is the lack of power consumption.
