Dc-Power And Battery Power; Dc Power Measurements; Buttons; External Fan Connection - Thundercomm TurboX C865 Dev Kit Hardware User's Manual

The DisplayPort audio is routed directly from the SM8250 SoC eDP interface pins to the Type C USB
connector.

3.10 DC-power and Battery Power

C865 DEV KIT power is supplied in one of the following ways:

8 V to 18 V power from a dedicated DC jack

8 V to 18 V power from the DC12V pins on the low-speed expansion connector
See Section 6 for details on C865 DEV KIT board DC power implementation.

3.11 DC power Measurements

The 96Boards specification calls for support for measuring board power consumption.
See Section 6 for details on C865 DEV KIT board DC power measurement.

3.12 Buttons

The 96Boards specification calls for the presence of two buttons, a power on/sleep button and a reset
button. C865 DEV KIT meets these requirements.
See Section 7 for details on C865 DEV KIT buttons.

3.13 External Fan connection

The 96Boards specification calls for support of an external fan. The external fan requirement can be
achieved using the 5 V or the DC-in.
Both are on the low-speed expansion connector.

3.14 UART

C865 DEV KIT supports one 4bit UART, and a 2bit UART (optional), and both of them are routed to
the low-speed expansion connector.
The 4bit UART comes directly from SoC pins to low-speed expansion connector. The 2bit UART is
optional an on-board UART debug log port via Micro USB port#21, or to be routed to low-speed
expansion connector. To use the port for log output, switch DIP_DEBUG_UART_SWITCH on DIP
switch (section 1.2.2#16) to ON.
