Matek F405-WMO Wing Flight Controller

The F405-WMO Flight Controller is engineered for reliable performance in fixed-wing and multi-rotor applications. Featuring the STM32F405 processor, built-in OSD, and versatile connectivity, it provides smooth control and precise handling. Compact and efficient, it’s a solid choice for pilots who want advanced functionality without unnecessary complexity.

Inav Mapping

ArduPilot Mapping

• ***  If connecting just one GPS to UART4(TX4/RX4),  pls set  SERIAL3_PROTOCOL = -1 or non “5”.   otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port(SERIAL3/UART5) configured for GPS protocol. 

SD card logging

• set LOG_BACKEND_TYPE = 1 (File)

Frsky Smartport Telemetry

• non-inverted (hacked) S.Port signal

• any spare Uart_TX
• SERIALx_BAUD   57
• SERIALx_OPTIONS  7
• SERIALx_PROTOCOL  4  or 10(for yaapu)

Relay(PINIO)

• PINIO1,  Vbat output ON/OFF, ON by default
• PINIO2,  PIO2 pad output Low/High Level,  Low Level by default

# GPIOs

• PA4  PINIO1  OUTPUT  GPIO(81)  LOW
• PB5  PINIO2  OUTPUT  GPIO(82)  LOW

# RCx_OPTION: RC input option

• 28   Relay1 On/Off
• 34   Relay2 On/Off

e.g.

• RELAY1_FUNCTION  1
• RELAY1_PIN       81
• RC7_OPTION   28    //Use CH7 of Transmitter to control Vbat output ON/OFF
• RELAY2_FUNCTION  1
• RELAY_PIN2     82    //PIO2 pad
• RC8_OPTION   34    //Use CH8 of Transmitter to control PIO2 Low/High Level

The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.

Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
