:::warning PX4 does not manufacture this (or any) autopilot. Contact the for hardware support or compliance issues. :::
The ® flight controller is a high-performance autopilot. It is an ideal choice for industrial drones and large-scale heavy-duty drones. It is mainly supplied to commercial manufacturers.
The flight controller adopts a modular design and can be matched with different base plates. You can design a dedicated carrier board for your UAV to improve the integration of commercial systems, reduce wiring, improve system reliability, and enhance your UAV competitiveness (for example, integrating airspeed sensors, telemetry or even a companion computer, in the carrier board). CUAV has also provided a variety of carrier boards for you to choose from.

:::note When it runs PX4 firmware, only 8 pwm works, the remaining 6 pwm are still being adapted, so it is not compatible with VOLT now. :::
:::warning The RCIN port is limited to powering the RC receiver and cannot be connected to any power/load. :::
The X7 AutoPilot can be triple-redundant on the power supply if three power sources are supplied. The power rails are: POWERA, POWERC and USB.
:::note The output power rails PWM OUT (0V to 36V) do not power the flight controller board (and are not powered by it). You must supply power to one of POWERA, POWERC or USB or the board will be unpowered. :::
Normal Operation Maximum Ratings
Under these conditions all power sources will be used in this order to power the system:
POWERA and POWERC inputs (4.3V to 5.4V)
USB input (4.75V to 5.25V)
:::tip Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected. :::
The X7 has over-current protection on the 5 Volt Peripheral and 5 Volt high power, which limits the current to 2.5A. The X7 has short circuit protection.
:::warning Up to 2.5 A can be delivered to the connectors listed as pin 1 (although these are only rated at 1 A). :::
The system's serial console and SWD interface operate on the DSU7 port. Simply connect the FTDI cable to the DSU7 connector (the product list contains the CUAV FTDI cable).

:::warning The SWD Vref pin (1) uses 5V as Vref but the CPU is run at 3.3V!
Some JTAG adapters (SEGGER J-Link) will use the Vref voltage to set the voltage on the SWD lines. For direct connection to Segger Jlink we recommended you use the 3.3 Volts from pin 4 of the connector marked DSM/SBUS/RSSI to provide Vtref to the JTAG (i.e. providing 3.3V and NOT 5V). :::

:::tip The manufacturer are the canonical reference for the X7. They should be used by preference as they contain the most complete and up to date information. :::
To for this target:
The and operate on the FMU Debug port (DSU7).
The debug port (DSU7) uses a connector and has the following pinout:
CUAV provides a dedicated debugging cable, which can be connected to the DSU7 port. This splits out an FTDI cable for connecting the to a computer USB port, and SWD pins used for SWD/JTAG debugging. The provided debug cable does not connect to the SWD port Vref pin (1).
Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. The complete set of supported configurations can be seen in the .
