• If sending highspeed serial data (eg. 921600 baud) to the board, use USART1(Serial1) or USART2(Serial6).

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)

DJI FPV OSD (ArduPilot 4.1)

https://ardupilot.org/plane/docs/common-msp-osd-overview.html

• OSD_TYPE = 3
• SERIAL4_PROTOCOL = 33
• MSP_OPTIONS = 0 (polling mode)

Relay(PINIO)

• PINIO_1, “Vxs” ON by default
• PINIO_2, Camera input switch, C1 by default

# GPIOs

• PA4 PINIO1 OUTPUT GPIO(81) LOW //”Vxs” power switch
• PB5 PINIO2 OUTPUT GPIO(82) LOW //Camera input 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 //”Vxs” power switch PINIO
• RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control Vxs ON/OFF
• RELAY_PIN2 82 //Camera input switch PINIO
• RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to control C1 or C2 input

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.

• F405-HDTE has INAV fw preloaded for QC

ArduPilot

• Support musical tone alarm with 5V passive buzzer
• Download latest ArduPilot firmware from HERE.

INAV

• With INAV firmware, DSHOT can not work on S3, S5,S7 because of DMA clash, pls use ONESHOT or MULTISHOT and calibrate ESC PWM range.
• Support 5V passive buzzer
• Download INAV firmware 4.1.x from our website.

BetaFlight

• If using 5V passive buzzer, CLI “set beeper_frequency = 2500”
• MATEKF405TE target was supported since BF4.3 RC3.
• set dshot_bitbang = ON when using X6 and X8 DSHOT,
• You may download BF 4.3 directly from BF configurator, BF 4.2.x from our website (click “Firmwares” button at upper right corner)
• Barometer SPL06-001 is not supported by Betaflight.
