X7 Wiring Quick Start

This quick start guide shows how to power the X7 flight controller and connect its most important peripherals.


Wiring Chart Overview

The image below shows how to connect the most important sensors and peripherals (except the motor and servo outputs). We'll go through each of these in detail in the following sections.

Main interface Function
POWER A Connect power module. Power input with analog voltage and current detection. Do not use a Digital PM on this connector!
POWER C Please connect CAN PMU SE to this interface; this interface is connected to UAVCAN power module
GPS&SAFETY Connect Neo series GPS or C-RTK 9P, including GPS, safety switch, buzzer interface.
UART 4 Can be used to connect to GPS, can be used as a second GPS
TELEM1/TELME2 Connect to the Telemetry System
TF CARD SD card for log storage (card pre-inserted in factory).
M1~M14 PWM signal output port, which can be used to control motors or steering gears; and M1~M12 also support dshot protocol
DSU7 Used for FMU chip debugging, read DEBUG device information
TYPE-C(USB) Connect to a computer for communication between the flight controller and the computer, such as loading firmware.
I2C1/I2C2/i2C4 Connect an I2C device such as an external compass.
CAN1/CAN2 Connect UAVCAN devices such as CAN GPS.
RC IN Including DSM, SBUS, RSSI signal input interface, DSM interface can be connected to DSM satellite receiver, SBUS interface to connect SBUS remote control receiver
RSSI RSSI for signal strength return module

Vehicle Front

If the controller cannot be mounted in the recommended/default orientation (e.g. due to space constraints) you will need to configure the autopilot software with the orientation that you actually used: Flight Controller Orientation.(for PX4 firmware, for Ardupilot firmware).



We recommend that you use UAVCAN GPS/RTK (such as Neo v2 pro); you only need to connect it to the CAN 1/2 interface; you can also use an ordinary GPS/RTK module; connect it to the GPS interface; it is commonly used now The GPS module generally integrates GPS, compass, safety switch, buzzer, and LED status light. The GPS module should be installed on the bracket and far away from other electronic devices. The installation direction is towards the front of the carrier (the NEO GPS arrow is in the same direction as the flight control arrow)


X7 may not be fully compatible with ordinary GPS modules of other manufacturers. If you need to use ordinary GPS, please choose NEO V2; for a better experience, we recommend you to use UAVCAN GPS.

safety switches

When you use NEO series GPS, there is no need to install additional safety switches.

If you are flying without GPS, you must connect the switch directly to the GPS1 port to be able to Arm and fly the drone. (If you use the old 6-pin GPS, please check the interface definition at the bottom to change the line).


When you use NEO series GPS, there is no need to install additional Buzzer.

If you use other manufacturers' gps, the buzzer may not work.

Radio Control

For your flight safety, it is recommended that whether you fly manually or automatically, please connect the handheld remote control (it can be used as an emergency machine, unless you are not proficient in operating the handheld remote control).

The figure below shows how you can connect to your remote control receiver (please find the Dupont cable in the package)



X7 is equipped with CAN PMU SE module, it supports 3~14s lithium battery, please connect the 6pin connector of the module to the flight control Power C interface


Telemetry (Radio) system

Using the telemetry system you can communicate with the drone through the ground station software. Monitor and control drones in flight. The airborne end of the telemetry system should be connected to the TELEM1/TELEM2 interface.


SD Card

The SD card is already installed on X7 when it leaves the factory, so you don't need to install it.


The motor/servo system is connected to the M1~M14 ports in the order specified for your carrier in the fuselage reference.


Servo power supply

The servo interface of X7 is completely isolated from the internal power supply of the flight controller. The flight controller will not supply power to the steering gear. If you need to supply power to the steering gear, please connect the BEC to any of the positive and negative stages of M1~M14 (M1~M14) The positive and negative times of the two are connected); then connect the Servo.
