here u had not mentioned what type board is.U can simply connect current meter in series with your main supply and calculate current consumptions and the u can calculate power required by formula V*I
Re: How do you calculate the power consumption of your board
hi
you can try by simulating the sch in spice or any other tool, i think it is the best way else you can try by doing it manually section by section
basically at design itself we calculate the power rating before selection of components
Re: How do you calculate the power consumption of your board
Hi
In begining state you calculate power by adding the max power consumption of each device for different volatage. Summation of power consumption of each device will be ur total power consumption
