+
+UART Mapping
+============
+The UARTs are marked RXn and TXn in the above pinouts. The RXn pin is the
+receive pin for UARTn. The TXn pin is the transmit pin for UARTn.
+
+- SERIAL0 -> USB
+- SERIAL1 -> USART1 (DJI / VTX, DMA capable)
+- SERIAL2 -> USART2 (Serial RC input, DMA capable)
+- SERIAL3 -> USART3 (User) (NO DMA)
+- SERIAL4 -> UART4 (User) (NO DMA)
+- SERIAL5 -> UART5 (ESC Telemetry) (NO DMA)
+- SERIAL6 -> USART6 (GPS) (NO DMA)
+
+RC Input
+========
+The default RC input is configured on the UART2(SERIAL1) RX2 input and can be used for all ArduPilot supported unidirectional receiver protocols except PPM.
+
+* SBUS/DSM/SRXL connects to the RX2 pin.
+* CRSF also requires a TX2 connection, in addition to RX2, and automatically provides telemetry.
+* FPort requires connection to TX2 and :ref:`SERIAL1_OPTIONS<SERIAL1_OPTIONS>` set to "7". See :ref:`common-FPort-receivers`.
+* SRXL2 requires a connection to TX2 and automatically provides telemetry. Set :ref:`SERIAL1_OPTIONS<SERIAL1_OPTIONS>` to “4”.
+
+OSD Support
+===========
+StellarF4 supports using its internal OSD using OSD_TYPE 1 (MAX7456 driver).
+External OSD support such as DJI or DisplayPort can be used simultaneously and is preconfigured on SERIAL3 but can be supported on any spare UART. See :ref:`common-msp-osd-overview-4.2` for more info.
+
+PWM Output
+==========
+StellarF4 supports up to 10 PWM/Dshot outputs. PWM1-4 outputs support Bi-Directional DShot.
+
+Channels 1-4 support bi-directional DShot. Channels 1-8 marked as M1-M8 on the board. Channels 9-10 marked as S1-S2 on the board. PWM outputs are grouped and every group must use the same output protocol:
+
+
+* 1, 2, 3, 4  are Group 1;
+* 5, 6, 7, 8  are Group 2;
+* 9           is Group 3;
+* 10           is Group 4;
+
+Battery Monitoring
+==================
+The board has 1 built-in voltage divider on an ADC input and 1x current ADC input and supports an external 3.3V based current sensor. The voltage input is compatible with 2~6S 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 (CURR pin)
+* :ref:`BATT_VOLT_MULT<BATT_VOLT_MULT__AP_BattMonitor_Analog>` = 11
+* :ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT__AP_BattMonitor_Analog>` = 52.7
+
+Compass
+=======
+StellarF4 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+
+Camera Switch
+=============
+GPIO 81 controls which camera input (CAM1 or CAM2) is applied to the internal OSD. A :ref:`RELAY <common-relay>` function can be enabled to control the switching.
+
+Loading Firmware
+================
+Firmware for these boards can be found at https://firmware.ardupilot.org in sub-folders labeled StellarF4.
+
+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.
