Serial Port Mapping

UART	Device	Port	Flow Control
USART1	/dev/ttyS0	GPS	-
USART2	/dev/ttyS1	TELEM1	Yes
USART3	/dev/ttyS2	TELEM2	Yes
UART4	/dev/ttyS3	TELEM4	-
USART6	/dev/ttyS4	RC	-
UART7	/dev/ttyS5	Debug Console	-
UART8	/dev/ttyS6	Reserved for optional onboard RTK module	-

INFO

UART8 is reserved for an optional onboard UM982 module footprint and is not intended for general external use.

Radio Control

A remote control (RC) radio system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes). You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver).

The ports and supported protocols are:

• DSM/SBUS/RSSI (FMU): SBUS, DSM/DSMX, ST24, SUMD, CRSF, and GHST receivers
• RC: PPM

For PPM and S.Bus receivers, a single signal wire carries all channels. If your receiver outputs individual PWM signals (one wire per channel) it must be connected via a PPM encoder.

GPS & Compass

PX4 supports GPS modules connected to the GPS port(s) listed below. The module should be mounted on the frame as far away from other electronics as possible, with the direction marker pointing towards the front of the vehicle.

The GPS ports are:

• GPS&SAFETY (FMU): 10-pin JST GH (Pixhawk Connector Standard) — GPS, compass (I2C), safety switch, buzzer, LED.

The GPS module's integrated safety switch is enabled by default (when enabled, PX4 will not let you arm the vehicle). To disable the safety switch press and hold it for 1 second. You can press the safety switch again to enable safety and disarm the vehicle.

PWM Outputs

This flight controller supports up to 8 FMU PWM outputs (MAIN).

DShot is not supported.

The 8 outputs are in 3 groups:

• Outputs 1-4 in group1 (Timer1)
• Outputs 5-6 in group2 (Timer4)
• Outputs 7-8 in group3 (Timer12)

All outputs within the same group must use the same output protocol and rate.

Debug Port

The PX4 System Console and SWD interface operate on the FMU Debug port (DSU7).

The debug port (DSU7) has the following pinout:

Pin	Signal	Volt
1	GND	GND
2	FMU_SWCLK	+3.3V
3	FMU_SWDIO	+3.3V
4	DEBUG RX	+3.3V
5	DEBUG TX	+3.3V
6	5V+	+5V

WARNING

The 5V+ pin (6) provides 5V, but the CPU logic runs at 3.3V!

Some JTAG/SWD adapters (like SEGGER J-Link) may use the Vref voltage pin to set the logic level on the SWD data lines. Connecting 5V to the adapter's Vtref can damage the CPU. For a direct connection to a Segger Jlink, we recommend you use a 3.3V source to provide Vtref to the JTAG adapter (i.e. providing 3.3V and NOT 5V).

Voltage Ratings

CORVON V5 must be powered from the POWER connector during flight, and may also be powered from USB for bench testing.

• POWER input: 4.75~5.5V
• USB input: 4.75~5.25V

The PM2 connector cannot power the flight controller. On PX4, do not use this interface.

Building Firmware

To build PX4 for this target:

make corvon_v5_default

Installing PX4 Firmware

The firmware can be installed in any of the normal ways:

• Build and upload the source

  make corvon_v5_default upload

• Load the firmware using QGroundControl. You can use either pre-built firmware or your own custom firmware.

INFO

If this target is not listed in QGroundControl, build and upload from source or load a custom firmware file (see Installing PX4 Main, Beta or Custom Firmware).

Supported Platforms / Airframes

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 Airframes Reference.
