CORVON 743v1

PX4 v1.18

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The CORVON 743v1 is a flight controller designed by Feikong Technology Co., Ltd under the CORVON brand. It features a powerful STM32H743 processor, dual high-performance IMUs (BMI088/BMI270), and an extensive array of interfaces.

With its highly integrated 36x36mm footprint and 9g weight, and specialized interfaces like a direct plug-and-play DJI O3 Air Unit connector, this flight controller is optimized for space-constrained FPV builds and agile multirotors that require top-tier processing power and sensor redundancy.

The board uses Pixhawk Autopilot Standard Connections.

INFO

Processors & Sensors

• FMU Processor: STM32H743
  • 32 Bit Arm® Cortex®-M7, 480MHz
  • 2MB Flash, 1MB RAM
• On-board Sensors:
  • Accel/Gyro: Bosch BMI088, BMI270

Power Configuration

The board has an internal voltage sensor and connections on the ESC connector for an external current sensor.

• The voltage sensor handles up to 6S LiPo batteries.
• Two onboard BECs provide robust peripheral power (9V 3A and 5V 3A).

Connectors & Pinouts

The following image shows the port connection details, including RC, UARTs, CAN, I2C, SWD Debug, and VTX connections.

Standard Serial Port Mapping

UART	PX4 Target Config	Default Usage
USART1	TELEM1	MAVLink
UART4	TELEM2	MAVLink
USART2	GPS1	GPS
USART3	TELEM3
UART8	URT6
USART6	RC	RC Input
UART7	TELEM4	ESC Telemetry

调试接口

The board features a 4-pin SWD Debug interface located on the right side of the board. This includes SWCLK, SWDIO, 3V3, and GND for full hardware debugging. While a dedicated UART isn't strictly reserved for the NSH console by default, the full-speed USB connection provides MAVLink Console access out of the box.

RC Input

RC Input is mapped to UART6 via the explicit SBUS/CRSF connector block.

• It fully supports PX4's standard RC_INPUT module protocols.
• The connector exposes both RX6 and TX6, which makes it fully capable of bidirectional receiver protocols such as TBS Crossfire (CRSF), ELRS, and FPort, as well as traditional single-wire standards like SBUS (which operates inverted on RX6).

Building/Loading Firmware

TIP

Most users will not need to build this firmware (from PX4 v1.18). It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target from source:

make corvon_743v1_default

Initial firmware flashing can be done over USB via QGroundControl. The bootloader status aligns with standard generic PX4 LED indications (Red = Bootloader/Error, Blue = Active/Activity, Green = Powered).
