Universal asynchronous receiver/transmitter (UART)
The NXP i.MX6UL CPU has eight UART interfaces, all of them capable of standard RS-232 serial communication.
On the ConnectCore 6UL:
- UART1 is connected to the Bluetooth chip (on modules with Bluetooth).
- The remaining UARTs are available for peripheral use.
On the ConnectCore 6UL SBC Express:
- UART4 is available on the expansion connector (2-wires, TTL level).
- UART5 is routed to the console connector.
On the ConnectCore 6UL SBC Pro:
- UART2 is available on a connector (4-wires, TTL level) with RTS/CTS lines multiplexed with CAN2 port. This port is shared with the XBee interface.
- UART3 is available on a connector (4-wires, RS232) with RTS/CTS lines multiplexed with CAN1 port.
- UART5 is routed to the console connector.
