QioTek Zealot F427

Note

This autopilot is supported in 4.1 and later firmware

The QioTek Zealot F427 is an internally vibration dampened autopilot with a protective CNC metal case for ruggedness. It features fully redundant sensors, expanded number of outputs, temperature controlled IMUs, and is the first high performance autopilot with integrated OSD chip.

VBAT Input

30V maximum input. A 5V, 1.5A regulator drops this input to the +5V used and supplied by the autopilot. Do not connect power to this input if Power Module 2 input is used as they share the BATT2 voltage monitoring circuitry. This connector is a JST-EH type.

SERVO VCC Rail Input

This provides a means to power servos attached to the output connector block by an external BEC or power source. Maximum power rating is 36V @ 20A.

RC Input

All compatible RC protocols can be decoded by attaching the Receiver’s output to the SBUS input pin next to the Servo/Output VCC input connector. Note that some protocols such as CRSF or, FPort including telemetry, require connection to, and setup of, one of the UARTs instead of this pin.

Default UART order

  • SERIAL0 = console = USB
  • SERIAL1 = Telemetry1 = USART1
  • SERIAL2 = Telemetry2 = USART2
  • SERIAL3 = GPS1 = USART3
  • SERIAL4 = GPS2 = UART4
  • SERIAL5 = USER = UART5

Dshot capability

All motor/servo outputs 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. The output groups that must be the same (PWM rate or Dshot, when configured as a normal servo/motor output) are: 1/2/3/4, 5/6/7/8, 9/10/11/12. Outputs 13 and 14 cannot support Dshot, only PWM.

Battery Monitor Settings

These should already be set by default. However, if lost or changed:

Enable Battery monitor with these parameter settings :

BATT_MONITOR =4

Then reboot.
