===Multiprotocol UARTs and CAN interfaces===
There are two UART multiprotocol ports (RS232 / RS485 / RS422) and one CAN interface available on SBC LYNX.
The two UART interfaces are named as MPUART0 (MX6UL UART8) and MPUART1 (MX6UL UART3) and are routed through two dual protocol ISL3330 transceivers(one for each port). {|class="wikitable" style="text-align: center;"! rowspan="3" style="text-align: center; font-weight: bold;" | P/N! colspan="5" style="text-align: center; font-weight: bold;" | MPUART0! colspan="5" style="text-align: center; font-weight: bold;" | MPUART1|-| colspan="2" style="text-align: center; font-weight: bold;" | Connector| rowspan="2" style="text-align: center; font-weight: bold;" | i.MX6UL's native port| rowspan="2" style="text-align: center; font-weight: bold;" | Pinout| rowspan="2" style="text-align: center; font-weight: bold;" | Electrical protocol| colspan="2" style="text-align: center; font-weight: bold;" | Connector| rowspan="2" style="text-align: center; font-weight: bold;" | i.MX6UL's native port| rowspan="2" style="text-align: center; font-weight: bold;" | Pinout| rowspan="2" style="text-align: center; font-weight: bold;" | Electrical protocol|-| style="text-align: center; font-weight: bold;" | Reference| style="text-align: center; font-weight: bold;" | Type| style="text-align: center; font-weight: bold;" | Reference| style="text-align: center; font-weight: bold;" | Type|-| style="text-align: center;" | XUBx0xxxxx| style="text-align: center;" | J34| style="text-align: center;" | Right-angle male DB9| style="text-align: center;" | UART8| style="text-align: center;" | aaa| style="text-align: center;" | RS232| style="text-align: center;" | J21| style="text-align: center;" | Right-angle male DB9| style="text-align: center;" | UART3| style="text-align: center;" | ccc| style="text-align: center;" | RS485|-| style="text-align: center;" | XUBx1xxxxx| style="text-align: center;" | J38| style="text-align: center;" | Phoenix| style="text-align: center;" | UART8| style="text-align: center;" | bbb| style="text-align: center;" | RS485| style="text-align: center;" | not populated| style="text-align: center;" | n/a| style="text-align: center;" | n/a| style="text-align: center;" | n/a| style="text-align: center;" | n/a|}
CAN interface is connected to MX6UL Flexcan1 controller through an SN65HVD23x CAN transceiver.
