Figure 1-5: Power Supply Diagram
The board can be powered by one of two 5V sources; P20, a 2.1 mm x 5.5 mm barrel type
plug (center positive) and J15, a Personal Computer (PC) type disk drive connector. The
barrel type plug connects to the 30W (5V @ 6A) power brick provided with the board while
the PC disk drive connector is provided for users who want to power their board while it
is installed inside a PC chassis. For applications requiring additional power, such as the
use of expansion cards drawing significant power, a larger AC adapter might be required.
If a different AC adapter is used, its load regulation should be less than 10% or better than
±10%. The power switch, SW1, turns the board on and off by controlling the 5V supply to
the board as shown in Figure 1-5, page
Note:
Never apply power to the power brick connector (P20) and the PC disk drive connector (J15)
at the same time as this will result in damage to the board.
The PWR Good LED lights when the 5V supply is applied.
