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.

e.g.

RELAY1_FUNCTION 1
RELAY_PIN 81 //10V switch PINIO

RELAY2_FUNCTION 1
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.

Flight Controller F405-miniTE

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

Tips

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

This DMA clash will be fixed from INAV 7.x.x.

IMU ICM42605 has been replaced with ICM42688-p since Jul.2022. Betaflight 4.2.x don’t support ICM42688-P. If Gyro/Acc can’t be detected after flashing it with 4.2.x. You may have received the latest batch of F405-miniTE. Pls reflash it with Betaflight 4.3.x.

Specifications

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
