Introduction
The development board is powered through a power adapter. The
input parameter is 100-240V~50/60MHz 0.5A, and the output is DC +5V
2A.
The input 5V power can generate 3.3v, 2.5v, 1.8v, 1.5v, 1.2v, 1.0v and
0.75v power required by DDR3, 17.4v, +5V and -5v required by MIPI DSI
interface and 16V, 10.4v, 9.9v, -7v required by RGB screen interface
through the power chip on the development board.
