PWM PWM1~PWM13 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. |

- ArduPilot Firmware
- INAV is expected to support H743 in 2.7.
- H743-MINI has betaflight firmware preloaded for QC
- BetaFlight Target MATEKH743 is supported since 4.3, pls download BetaFlight firmware 4.2.x from our website.
- If you flash ArduPilot firmware via BetaFlight configurator. there is a known issue that flash process will freeze at 50% if “full chip erase” is selected. It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware http://www.mateksys.com/?p=6905
- Crossfire support only exists in “latest” 4.1, not stable 4.0.x, if you load “latest” then Set SERIAL7_PROTOCOL = 23, RSSI_TYPE = 3
