HDMI audio is carried over the HDMI signals to the HDMI connector (J6).
5.10 Input DC-power
The 96Boards specification calls for power to be provided to the board in one of the following ways:
● 8V to 18V input voltage power supplied from a dedicated DC jack
● 8V to 18V input voltage power supplied from the SYS_DCIN pins on the Low Speed Expansion Connector
Please see section 10 for detailed information on DB8 implementation of DC Power. Note that the DB8 does not
support USB Type C.
5.11 Measurements
The 96Boards specification calls for support for measuring power consumptions of the board.
Please see the power measurement section for detailed information on DB8 power measurement
implementation.
5.12 Buttons
The 96Boards specification calls for the presence of two buttons, a Power on/sleep button and a Reset button.
This board meets these requirements. Please see section 11 for detailed information on the buttons of the DB8.
5.13 UART
The 96Boards specification calls for support for one SoC UART and an optional second UART both to be routed to the Low
Speed Expansion Connector.
The DB8 routes 2 UARTs to the low speed connector.
5.14 System and user LEDs
The 96Boards specifications 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:
• WiFi activity LED – DB8 drives this Yellow LED via MPP_2, an IO from the PMIC.
• BT activity LED – DB8 drives this Blue LED via MPP_4 an IO from the PMIC.
Four User-LEDs:
The four user LEDs are surface mount Green in 0603 size located next to the two USB type A connector and labeled ‘USER
