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.

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. Tab Title * F405-TE has INAV fw preloaded for QC * set BLHeli32 ESC PWM rate to 48KHz or higher in BLHeliSuite **ArduPilot** * Support musical tone alarm with 5V passive buzzer * Download ArduPilot firmware from [HERE](https://firmware.ardupilot.org/). **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.** * Download INAV firmware 4.1.x from our website. INAV5.x or newer directly from INAV configurator [**BetaFlight**](https://www.premium-modellbau.de/lexikon-betaflight/) * If using 5V passive buzzer, CLI “set beeper\_frequency = 2500” * **MATEKF405TE target was supported since BF4.3.** * **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](https://www.premium-modellbau.de/lexikon-betaflight/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
