→Multiprotocol UARTs and CAN interfaces
There are two UART multiprotocol ports (RS232 / RS485 / RS422) and one CAN interface available on SBC LYNX.
UART interfaces are named as MPUART0 and MPUART1. They are associated to i.MX6UL's native UART8 and UART3 respectively. They are routed to connectors through Intersil ISL3330 transceivers (one for each port).
Generally speaking, multiprotocol UARTs
