UART {3/6}
The 96Boards specifications calls for a 4-wire UART implementation, UART0 and an optimal second
2-wire UART, UART1 on the Low Speed Expansion Connector.The HiKey960 Development Board
implements UART3 as a 4-wire UART that connects directly to theMT6797 SoC. These signals are
driven at 1.8V.The HiKey960 Development Board implements UART6 as a 2-wire UART that connects
directly to theMT6797 SoC. These signals are driven at 1.8V.
I2C {0/1}
The 96Boards specification calls for two I2C interfaces to be implemented on the Low Speed Expansion
Connector.
The HiKey960 Development Board implements both interfaces named I2C0 and I2C7. They connect
directly to the Kirin960 SoC. Each of the I2C lines is pulled up to VIO18_PMU via 1K resistor.
