UART {0/1}
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 ROCK960 Board implements UART0 as a 4-wire UART that connects directly to the RK3399
SoC. These signals are driven at 1.8V.
The ROCK960 Board implements UART1 as a 2-wire UART that connects directly to the RK3399
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 ROCK960 Board implements both interfaces named I2C1 and I2C6. They connect directly to
the RK3399 SoC.
GPIO {A-L}
The 96Boards specification calls for 12 GPIO lines to be implemented on the Low
Speed Expansion Connector. Some of these GPIOs may support alternate functions
for DSI/CSI control
