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 welded to generate 3.3V, 1.5V, and 1.0V. The rated current
