| PWM S1~S9 & LED are Dshot and PWM capable. However, 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. | S1 | PWM1 GPIO50 | PB7 TIM4_CH2 | Group1 |

Important Notes & Tips
- *** known issue/bug: BetaFlight doesn’t support barometer DPS310 working with STM32F405.
- F405-SE has INAV firmware preloaded for QC
- INAV2.5.1 downloaded from configurator doesn’t support new barometer DPS310. download customized firmware from here.
- DPS310 will be supported officially by INAV2.6 and new configurator.
- ArduPilot Firmware “MATEKF405-WING″ prior to June 25 does not support the onboard barometer DPS310. pls download firmware from “latest” folder.
inav_2.5.1_MATEKF405SE_DPS310.hex
If Baro can’t be detected. In INAV CLI mode, type command
- set baro_hardware = DPS310
- save
betaflight_4.2.0_MATEKF405SE.hex
- known issue/bug: DPS310 will not work even if you type the following CLI command.
- set baro_bustype = I2C
- set baro_i2c_device = 1
- set baro_i2c_address = 118
- set baro_hardware = DPS310
- save
