Power Calculation Example
In the example system listed below, the maximum current draw on the Power
Supply’s 3.3V output by all of the modules will be 0.215 A.
Subtracting 0.215A from the Power Supply total output of 1.5 A shows that
1.285A will be available via the 5.5V output:
(1.5A – 0.215A = 1.285A)
Because the maximum current draw on the 5V output would be 0.65A as listed
in the following table, any of the available Power Supplies could be used for this
system.
