PWM level switching

The flight controller outputs a default voltage level of 3.3V. When the signal cable for your device is excessively long, exceeding 75cm, it is recommended to change it to a 5.0V voltage level. However, please ensure that your external device supports this voltage (please consult with your hardware device manufacturer). The modification method is as follows:
After connecting to Mission Planner, search for the BRD_PWM_VOLT_SEL parameter in the complete parameter list. The default value is 0, representing a 3.3V level. Change it to 1, write the parameter, and restart the flight controller or re-power it for the change to take effect.

PWM Connector Recommendations

The PWM terminals on the X6 flight controller feature a custom 2.6mm pitch. It is recommended to use Futaba 3-pin Dupont right-angle headers, as shown in the figure below:

Wiring instructions

The following wiring diagram introduces the wiring method for a conventional vertical takeoff and landing (VTOL) drone. The wiring method is for reference only. Users need to add devices and adjust the interface methods according to their own drone models and requirements. Please refer to the previous interface descriptions for the functions of each interface.

Safety Instructions

This product is not suitable for individuals under the age of 18. Those under 18 should use it under adult supervision.
This product is an open-source flight controller, and users must have professional knowledge of open-source drones to correctly configure and operate them.
Do not fly in strong winds.
The flight controller itself is not waterproof, so do not fly in the rain.
Please comply with local laws and regulations. Without local permission, do not fly in crowded areas, near train stations, airports, or other sensitive areas to avoid endangering public safety.
Before takeoff, carefully inspect to ensure all connections are secure, all equipment is functioning properly, and all control responses are correct to prevent accidents.
Perform routine maintenance before and after each flight, checking for loose hardware connections, damaged motor blades, and the tightness of screws.
The rapidly spinning propellers are highly dangerous. Please be safe and keep away from crowds when flying. Never operate or fly while under the influence of alcohol, fatigued, or in any other impaired mental state.
