In Flight Controller and PDB part, we mainly sell Matek, hobbyeagle and some of the DJI products. It is certain that all of these are original, not from some duplicated ones such as OCDAYS (I am not saying these duplicated products are not good). For some new released products like Matek F411 Flight controller, we have not uploaded to the platform, but you can still contact with us to order from factory directly and make shipping for you.

ArduPilot mapping

PWM
PWM1~PWM13 are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs.
If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.

ArduPilot Relay(PINIO)

  • Camera-1 and 8V On by default

  • Make sure 2 cameras are set with identical video format, both PAL or both NTSC.

# GPIOs

  • PD10 PINIO1 OUTPUT GPIO(81)   //8V power ON/OFF switch

  • PD11 PINIO2 OUTPUT GPIO(82)   //Camera switch

# RCx_OPTION: RC input option

  • 28   Relay On/Off

  • 34   Relay2 On/Off

  • 35   Relay3 On/Off

  • 36   Relay4 On/Off

e.g.

  • RELAY_PIN       81    //8V switch GPIO

  • RC7_OPTION   28    //Relay On/Off, Use CH7 of Transmitter to switch Vsw

  • RELAY_PIN2     82    //Camera switch GPIO

  • RC8_OPTION   34    //Relay2 On/Off, Use CH8 of Transmitter to switch camera

or

  • RELAY_PIN3       81    //8V switch GPIO

  • RC9_OPTION     35    //Relay3 On/Off, Use CH9 of Transmitter to switch Vsw

  • RELAY_PIN4       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.
