2.1 Power Requirements

The DP83826AEVM power is supplied by the 5-12V input connection in the image below. Single supply operation uses on-board LDOs to generate the voltages required for operating various sections of the EVM. Power can also be supplied externally to individual voltage rails. The micro-USB supplies power to the on-board LDOs that power all microcontroller related components.

Note:

Before supplying power at the 5-12V input, make sure the correct shunts are added to the appropriate headers to properly operate the on-board LDOs as seen in the figure below.
