+## Pinout
+![ZeroOneX6_Air Pinout](https://github.com/ZeroOne-Aero/ardupilot/blob/ZeroOneX6_Air/libraries/AP_HAL_ChibiOS/hwdef/ZeroOneX6_Air/ZeroOneX6_AirSeriesPinout.jpg "ZeroOneX6_Air")
+
+## 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 | MCU PINS | DMA |
+| :-----: | :------: | :------: | :------:|
+| SERIAL0 | OTG1 | USB |
+| SERIAL1 | Telem1 | UART7 |DMA Enabled |
+| SERIAL2 | Telem2 | UART5 |DMA Enabled |
+| SERIAL3 | GPS1 | USART1 |DMA Enabled |
+| SERIAL4 | GPS2 | UART8 |DMA Enabled |
+| SERIAL5 | Telem3 | USART2 |DMA Enabled |
+| SERIAL6 | UART4 | UART4 |DMA Enabled |
+| SERIAL7 | OTG-SLCAN| USB |
+
+## RC Input
+The remote control signal should be connected to the SBUS RC IN port.It will support ALL unidirectional RC protocols.
+
+## PWM Output
+The X6_Air flight controller supports up to 15 PWM outputs.
+First 8 outputs (labelled 1 to 8) are controlled by a dedicated STM32F103 IO controller.
+The remaining 7 outputs (labelled 9 to 15) are the "auxiliary" outputs. These are directly attached to the STM32H753 FMU controller .
+All 15 outputs support normal PWM output formats. All 15 outputs support DShot, except 15.
+
+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 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 |
+ |
+ FMU Pins |
+
+ Name | Value | Option | | Name | Value | Option |
+ M1 | 101 | MainOut1 | | A9 | 50 | AuxOut1 |
+ M2 | 102 | MainOut2 | | A10 | 51 | AuxOut2 |
+ M3 | 103 | MainOut3 | | A11 | 52 | AuxOut3 |
+ M4 | 104 | MainOut4 | | A12 | 53 | AuxOut4 |
+ M5 | 105 | MainOut5 | | A13 | 54 | AuxOut5 |
+ M6 | 106 | MainOut6 | | A14 | 55 | AuxOut6 |
+ M7 | 107 | MainOut7 | | A15 | 56 | |
+ M8 | 108 | MainOut8 | | | | |
+
+
+## Battery Monitoring
+The X6_Air flight controller has one six-pin power connectors, supporting CAN interface power supply.
+This is set by default in the firmware and shouldn't need to be adjusted.
+
+## Compass
+The X6_Air flight controller built-in industrial-grade electronic compass chip IST8310.
+
+## Analog inputs
+The X6_Air flight controller has 2 analog inputs.
+- ADC Pin12 -> ADC 6.6V Sense
+- ADC Pin13 -> ADC 3.3V Sense
