2.1.3 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 the add-on devices. Table 2-3 shows the design’s power allocations. Again, the input supply must be capable of supplying the power needs of your application.

Table 2-3 Power Allocation
Function Power Description
Processor Core TBD Processor, DDR Memory
Memory, Non-Volatile TBD xSPI NOR, eMMC, UFS, etc.
On-Board Peripherals TBD Ethernet, CPLD, Boot Logic, etc.
USB Port(s) TBD Type A Port(s), Type C
Expansion Interface(s) TBD PCIe, PCIe M.2, SGMII Expansion
Camera Port(s) TBD RPI Camera(s), Camera Expansion
Display(s) TBD DisplayPort/HDMI Panel(s), DP/HDMI Transceiver(s)
