6.12 External Fan Connection

The SD 600eval board can drive 5V or 12V DC fan. The power for driving external Fan is available on the Low Speed Expansion

connector.

The 96Boards CE specification calls for support for one SoC UART and an optional second UART, both to be routed to the Low

Speed Expansion Connector.

The SD 600eval meets these requirements by routing APQ8064 GSBI 1 port as full UART and GSBI 7 port as debug UART, to low

speed expansion connector.

The 96Boards CE specification calls for the presence of button switch to manually Power up/down & Reset the board.

The SD 600eval meets the board reset requirement. The power button SW2 can be used to sleep/wakeup the board. The reset

button SW3 is used to reset the board.

Additionally, SD 600eval also provides a user configurable switch SW1 on board.

The push-button SW2 serves as the sleep/wakeup button. Upon applying power to the board, the boot process will start. Once

the board boot process is completed, user can go to Power off selection on Android UI by pressing the button for more than 5

seconds. If the board is in a sleep mode, pressing the power button will wake up the board

(Above functionality of power button is tested over Android release)

The on board SW3 push-button serves as a reset button. Button press with duration of more than 10 seconds will cause a

system reset.

The 96Boards CE specification calls for six LEDs to be implemented on the board. The specification defines the LEDs color and

mechanical location on the board.

Two activity LEDs:

• Wi-Fi activity LED is a surface mount Yellow color LED, 0603 size. The SD 600eval board drives this Yellow LED via

MPP_07 (PMIC GPIO).

• BT activity LED is a surface mount Blue color LED, 0603 size. The SD 600eval board drives this Blue LED via MPP_08 (PMIC

GPIO).

Four User-LED's:

The four user LEDs are surface mount Green LED, 0603 size, located next to the two USB type A connector and labeled

'USER LEDS 3 2 1 0'.
