CLI “set telemetry_inversion = ON”  for Frsky SmartPort working on TX pin directly.

If FC can’t be connected to INAV configurator after flashing, unstall COM port driver, then install folowing driver for WIN10X64

Tips
  • F7 32K loop can’t be supported now. Max. 32K/8K or 16k/16K with current BF3.2.3,  Max.32K/16K with last 3.3 build.
  • CLI “defaults” after reflashing
  • Rubber anti-vibration standoffs are necessary to avoid the vibration woes.
  • Put a piece of sponge on the barometer to reduce the impact of airflow.
  • If you are using 5V VTX, Pls power the VTX via the 5V pad on FCHUB.  The ribbon cable can’t bear heavy current.
  • SBUS, DSM, IBUS, SUMD can be connected to any unused UART_RX.
  • PPM share RX2 pad
  • Frsky SmartPort, Tramp & smartaudio protocol can be connected to any unused UART_TX
  • S6 pad (PA8) can be resourced to Camera Control
  • pwm pad (PB8) can be resourced to Camera Control, LED_STRIP, or Motor
  • SD Card, FAT32  C10, 1~32G,  But max.4G space can be used in Blackbox.
