# GPIOs

• PD10 PINIO1 OUTPUT GPIO(81)   //Vsw pad power switch
• PD11 PINIO2 OUTPUT GPIO(82)   //Camera switch

# RCx_OPTION: RC input option

• 28   Relay1 On/Off
• 34   Relay2 On/Off
• 35   Relay3 On/Off
• 36   Relay4 On/Off

e.g.

• RELAY1_PIN       81    //Vsw GPIO
• RC7_OPTION    28    //Relay On/Off, Use CH7 of Transmitter to switch Vsw
• RELAY2_PIN     82    //Camera switch GPIO
• RC8_OPTION    34    //Relay2 On/Off, Use CH8 of Transmitter to switch camera

or

• RELAY3_PIN       81    //Vsw GPIO
• RC9_OPTION      35    //Relay3 On/Off, Use CH9 of Transmitter to switch Vsw
• RELAY4_PIN       82    //Camera switch GPIO
• RC10_OPTION    36    //Relay4 On/Off, Use CH10 of Transmitter to switch camera

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:

• 2 x JST-SH1.0_8pin connectors
• 1 x JST-GH-4P to JST-GH-4P cable for CAN port, 20cm
