+## 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
+
+RC input is configured on the UART4(SERIAL4). It supports all serial RC protocols. SERIAL2_PROTOCOL=23 by default.
+
+   
+## OSD Support
+
+StellarH7V2 supports using its internal OSD using OSD_TYPE 1 (MAX7456 driver). External OSD support such as DJI or DisplayPort is supported using any spare UART. See :ref:`common-msp-osd-overview-4.2` for more info.
+
+## PWM Output
+
+StellarH7V2 supports up to 10 PWM outputs. All outputs support DShot.
+
+
+## Battery Monitoring
+
+The board has 1 built-in voltage dividers and 2x current ADC. support external 3.3V based current sensor
+
+
+## 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.
