Remap S9 as PWM camera control
- resource camera_control A08
- PWM camera control doesn’t 100% work with every camera due to the camera voltage tolerance.

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. |

Important Notes & Tips
- *** BetaFlight firmwares 4.2.x in “Release” branch don’t support barometer DPS310, pls downoad latest 4.3.x from “development” branch.
- or download betaflight 4.2.x from “Firmwares” link
- F405-SE has INAV firmware preloaded for QC
- INAV2.5.1 downloaded from configurator don’t support new barometer DPS310. Pls use INAV2.6 and new configurator.
- ArduPilot Firmware “MATEKF405-WING″ has supported the onboard barometer DPS310 since Plane-4.0.6 & Copter-4.0.4
