+## 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
+
+## Pinout

+
+
+## 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.
+| Name    | Function |DMA|
+| ------- | -------- |---|
+| SERIAL0 | OTG1     ||
+| SERIAL1 | UART7    |DMA Enabled |
+| SERIAL2 | UART5    |DMA Enabled |
+| SERIAL3 | USART1   |DMA Enabled |

+
+## 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.
+
+## 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
