Power Supply

3.3.1

Introduction

5V power (Input: 100-240V~50/60MHz 0.5A, output: DC +5V 2A) The

development board generates 3.3V, 2.5V, 1.5V, 1.2V, 1.0V, and 0.75V
(required by DDR3).

One redundant power location is reserved on the development board.

A LDO can be wielded to generate 3.3V, 1.5V, and 1.0V. The rated current
is 2A. When the redundant power is used to replace the main power, you
need to take off the main power's magnetic beads to avoid the power
conflicts.
