External Fan Connection
The 96Boards specification calls for support for an external fan. That can be achieved by using the 5V
orthe SYS_DCIN (12V), both present on the Low Speed Expansion connector.
UART
The Hikey960 Development Board has two UART ports (UART6 / UART3), both present on the Low
Speed Expansion connector. They are routed to the UART6 (UART1TxD, UART1RxD) and UART3
(UART3TxD, UART3RxD, UART3CTS, UART3RTS) interface of Kirin960 separately. The UART6
isused for the serial console output.
Buttons
The Hikey960 Development Board presents one button. It is Power key which also can be used as
Resetkey. The power ON/OFF and RESET signals are also routed to the Low Speed Expansion
