Matek F405-miniTE Flightcontroller F405 Ardupilot, INAV, Betaflight

STM32F405RGT6, ICM42605, SPL06, OSD, 6x UARTs, 1x I2C, 12x PWM outputs, BEC 5V & 10V.

INAV firmware, S3, S5,S7 DSHOT not working because of DMA clash,  pls use ONESHOT or MULTISHOT and calibrate ESC PWM range.

If you stick with Dshot, you may use ArduPilot or BetaFlight firmware.

The new features of F405-miniTE compared with F722-miniSE(EOL)

• F405 has 1MB flash which can run with ArduPilot. even with INAV firmware, some features will be removed on F722 due to limited flash.
• The advantage of F722 is all UARTs have builtin inversion which is not needed when CRSF protocol is widely used on new receivers.
• Redesigned target MATEKF405TE support 8x bi-directional DSHOT.
• Support DJI air unit PnP, and a 10V BEC for DJI OSD or analog VTX
• Compared with F722-miniSE 8motors or 6motor+2servos, F405-miniTE support 8motors+3servos in INAV/BF multirotor mixer
• InvenSense GEN3 IMU ICM42605

INAV/BF mapping

ArduPilot mapping

• 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, 10V On by default
• PINIO_2, PB5 pad, spare

# GPIOs

• PA4 PINIO1 OUTPUT GPIO(81) LOW //10v power switch
• PB5 PINIO2 OUTPUT GPIO(82) LOW //spare

# 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 //10V switch PINIO
• RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control 10V ON/OFF
• RELAY_PIN2 82 //spare
• 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.

Important Tips

• F405-miniTE has INAV fw 3.0.2 preloaded for QC

ArduPilot
