ZeroOneX6 Flight Controller

The ZeroOne X6 is a flight controller manufactured by ZeroOne, which is based on the open-source FMU v6X architecture and Pixhawk Autopilot Bus open source specifications.

Features:

• Separate flight control core design.
• MCU
  STM32H753IIK6 32-bit processor running at 480MHz
  2MB Flash
  1MB RAM
• Sensors
• IMU:
  Internal Vibration Isolation for IMUs
  IMU constant temperature heating(1 W heating power).
  With Triple Synced IMUs, BalancedGyro technology, low noise and more shock-resistant:
  IMU1-ICM45686(With vibration isolation)
  IMU2-BMI088(With vibration isolation)
  IMU3- ICM45686(No vibration isolation)
• Baro:
  Two barometers:2 x ICP20100
  Magnetometer: Builtin RM3100 magnetometer

UART Mapping

The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the receive pin for UARTn. The Tn pin is the transmit pin for UARTn.

RC Input

The remote control signal should be connected to the SBUS RC IN port or DSM/PPM RC Port.It will support ALL unidirectional RC protocols.

PWM Output

The X6 flight controller supports up to 16 PWM outputs.
First first 8 outputs (labelled 1 to 8) are controlled by a dedicated STM32F103 IO controller. These 8 outputs support all PWM output formats, but not DShot.
The remaining 8 outputs (labelled 9 to 16) are the "auxiliary" outputs. These are directly attached to the STM32H753 FMU controller .
All 16 outputs support normal PWM output formats. All FMU outputs, except 15 and 16, also support DShot.

The 8 IO PWM outputs are in 4 groups:

• Outputs 1 and 2 in group1
• Outputs 3 and 4 in group2
• Outputs 5, 6, 7 and 8 in group3

The 8 FMU PWM outputs are in 4 groups:

• Outputs 1, 2, 3 and 4 in group1
• Outputs 5 and 6 in group2
• Outputs 7 and 8 in group3

Channels within the same group need to use the same output rate. If any channel in a group uses DShot then all channels in the group need to use DShot.

GPIO

All PWM outputs can be used as GPIOs (relays, camera, RPM etc). To use them you need to set the output’s SERVOx_FUNCTION to -1. The numbering of the GPIOs for PIN variables in ArduPilot is:
Io pins
M1 Mainout1:101
M2 Mainout2:102
M3 Mainout3:103
M4 Mainout4:104
M5 Mainout5:105
M6 Mainout6:106
M7 Mainout7:107
M8 Mainout8:108

M10 AUXOUT2:51
M11 AUXOUT3:52
M12 AUXOUT4:53
M13 AUXOUT5:54
M14 AUXOUT6:55
M15 56
M16 BB Blue GPO pin 3:57

Battery Monitoring

The X6 flight controller has two six-pin power connectors, supporting CAN interface power supply.
These are set by default in the firmware and shouldn't need to be adjusted.

Compass

The X6 flight controller built-in industrial-grade electronic compass chip RM3100.

Analog inputs

The X6 flight controller has 2 analog inputs.

• ADC Pin12 -> ADC 6.6V Sense
• ADC Pin13 -> ADC 3.3V Sense
• RSSI input pin = 103
