Tips
- F405-WMN has INAV fw preloaded for QC
- Download INAV firmware 4.1.x from our website. Target MATEKF405TE is not listed in INAV configurator 4.x.x,
- You may download INAV fw 5.0 or newer directly from INAV configurator 5.x or newer.

| Mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group. |

- *** If connecting just one GPS to UART4(TX4/RX4), pls set UART5 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.
- If sending highspeed serial data (eg. 921600 baud) to the board, use USART1(Serial1) or USART2(Serial6).

Relay(PINIO)
- PINIO1, PIO1 pad, Low Level by default
- PINIO2, Camera switch, C1 ON by default
# GPIOs
- PA4 PINIO1 OUTPUT GPIO(81) LOW //PIO1 pad
- PB5 PINIO2 OUTPUT GPIO(82) LOW //camera switch
# RCx_OPTION: RC input option
- 28 Relay On/Off
- 34 Relay2 On/Off
- 35 Relay3 On/Off
- 36 Relay4 On/Off
e.g.
- RELAY_PIN 81 //PIO1 GPIO
- RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control PIO1 Low/High Level
- RELAY_PIN2 82 //Camera switch GPIO
- RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to control high/low level on PB5 pad
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.
