        ArduPilot Mapping:

        RC INPUT

        RC input is configured on the USART2(SERIAL2). It supports all serial RC protocols. SERIAL2_PROTOCOL=23 by default.

        • PPM is not supported.
        • CRSF requires Tx2 & Rx2 connection, and set SERIAL2_OPTIONS to “0” (default).
        • SBUS/DSM/SRXL connects to the Rx2 pin, but SBUS requires that the SERIAL2_OPTIONS be set to “3”.
        • FPort requires connection to Tx2, and set SERIAL2_OPTIONS to “7”. If Telemetry doesn’t work, try set  SERIAL7_OPTIONS = 135.
        • SRXL2 requires a connection to Tx2, and automatically provides telemetry. Set SERIAL2_OPTIONS to “4”.
        • Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM. See Radio Control Systems for details.

        ArduPilot Relay(PINIO)

        • 9V output ON by default
        • PC13 PINIO1 OUTPUT GPIO(81)   //9V power switche.g.
        • RELAY_PIN       81    // PINIO1 GPIO
        • RC7_OPTION   28    //Relay On/Off, Use CH7 of Transmitter to set 9V ON/OFF

        The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.

        Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.


        Package Includes:
