2 IntroductionSBC LYNX – also denoted by product family code SXUBx – is designed for an industrial applications, in particular for the control and supervision. SBC LYNX collects information from ethernet/wifi/RS485/RS232/CAN and other peripherals, analysis data and provides information to webservers or dedicated local displays. It can also act on Ethernet networking, storing data on SD card and optionally on NAND/NOR flash.

1SBC LYNX (SXUBx) supports a broad range of interface options dedicated to embedded applications, including Ethernet support, WiFi, SD card socket, RGB display and capacitive touchscreens, USB, CAN, UARTs, GPIOs.

5.14 UARTs/CANThere 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 UART7) and MPUART1 (MX6UL UART3) and are routed through two dual protocol ISL3330 transceivers.

CAN interface is connected to MX6UL Flexcan1 controller
