6.1 UART {0/1}
The 96Boards specifications calls for a 4-wire UART implementation, UART0 and an optional second 2-wire UART, UART1
on the Low Speed Expansion Connector.
The DB8 implements UART0 as a 4-wire UART that connects directly to the APQ8096 SoC. These signals are driven at
1.8V.
The DB8 implements UART1 as a 2-wire UART that connects directly to the APQ8096 SoC. These signals are driven at
1.8V.
