+
+## Wiring Diagram
+
+
+## UART Mapping
+
+The UARTs are marked Rx* and Tx* in the above pinouts. The Rx* pin is the
+receive pin for UART*. The Tx* pin is the transmit pin for UART*.
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> USART1 (User)
+ - SERIAL2 -> USART2 (User)
+ - SERIAL3 -> USART3 (User)
+ - SERIAL4 -> UART4  (Serial RC input)
+ - SERIAL6 -> USART6 (User)
+ - SERIAL7 -> USART6 (User)
+ - SERIAL8 -> USART6 (User)
+
+## CAN and I2C
+
+StellarH7V2 supports 1x CAN bus and 1x I2C bus
+multiple CAN peripherals can be connected to one CAN bus in parallel. similarly for I2C bus.
+
+## RC Input
+
+The default RC input is configured on the UART4 RX4 input and can be used for all ArduPilot supported unidirectional receiver protocols. 
+* PPM is not supported.
+* SBUS/DSM/SRXL connects to the RX4 pin.
+* FPort requires connection to TX4 and RX4 via a bi-directional inverter. See :ref:`common-FPort-receivers`.
+* CRSF also requires a TX4 connection, in addition to RX6, and automatically provides telemetry.
+* SRXL2 requires a connection to TX4 and automatically provides telemetry. Set :ref:`SERIAL4_OPTIONS<SERIAL4_OPTIONS>` to “4”.
+
+
+## OSD Support
+
+StellarH7V2 supports using its internal OSD using OSD_TYPE 1 (MAX7456 driver). Simulatenous DisplayPort OSD operation  is preconfigured on SERIAL 6 but requires OSD_TYPE2 = 5. See :ref:`common-msp-osd-overview-4.2` for more info.
+
+## PWM Output
+
+StellarH7V2 supports up to 10 PWM outputs. All outputs support DShot.
+
+All the channels support DShot. Channels 1-4 support bi-directional DShot. PWM outputs are grouped and every group must use the same output protocol:
+* 1, 2,are Group 1;
+* 3 - 6 are Group 2;
+* 7 - 9 are Group 3;
+
+
+## Battery Monitoring
+
+The board has 1 built-in voltage dividers and 2x current ADC. support external 3.3V based current sensor
+
+The voltage input is compatible with 2~8S LiPo batteries.
+The default battery parameters are:
+* :ref:`BATT_MONITOR<BATT_MONITOR>` = 4
+* :ref:`BATT_VOLT_PIN<BATT_VOLT_PIN__AP_BattMonitor_Analog>` = 10
+* :ref:`BATT_CURR_PIN<BATT_CURR_PIN__AP_BattMonitor_Analog>` = 11
+* :ref:`BATT_VOLT_MULT<BATT_VOLT_MULT__AP_BattMonitor_Analog>` = 11
+* :ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT__AP_BattMonitor_Analog>` = 10
+* :ref:`BATT2_CURR_PIN<BATT2_CURR_PIN__AP_BattMonitor_Analog>` = 7
+
+
+## Compass
+
+StellarH7V2 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+
+
+## Loading Firmware
+Firmware for these boards can be found at https://firmware.ardupilot.org in sub-folders labeled StellarH7V2.
+
+Initial firmware load can be done with DFU by plugging in USB with the
+boot button pressed. Then you should load the "ardu*_with_bl.hex" firmware, using your favourite DFU loading tool. eg STM32CubeProgrammer
+
+Subsequently, you can update firmware with Mission Planner.
+
+
+## Camera Switch
+GPIO 81 controls which camera input (CAM1 or CAM2) is applied to the internal OSD. A RELAY function can be enabled to control the switching.
