FAQ & Known Issues

  • Enabling DShot for motor 6: Instructions
  • The SI pin on the PDB connector does not have a voltage divider. If the PDB connector is used as input for the battery voltag measurement, the PDB has to have a voltage divider, or the MCU on the board will be immediately and permanently destroyed by the battery voltage! (The SI pad on the board does have a voltage divider. Use this if your PDB does not have a voltage divider.)
