The board has ethernet port, USB, CAN, LED and a custom board-to-board expansion connector. For this board a DHCOM i.MX6ULL SoM configuration without WiFi/BT is used. The interface is used for the SD card instead. Make this adjustment by using a separate DT include file.

The system has two ethernet ports, two CANs, RS485 and RS232, USB, capacitive buttons and an OLED display. For this board a DHCOM i.MX6ULL SoM configuration without WiFi/BT is used. The interface is used for the SD card instead.
