2.1.2 Power Budget Considerations

The exact power required for the EVM is largely dependent on the application, usage of the on-board peripherals, and power needs of add-on devices. Table 2-2 shows the designs power allocations. (Again, the input supply must be capable of supplying the power needs for your application.)
