+EXPANSION BOARD
+
+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. Default protocols are shown below but may be changed by the user.
+
+   -  SERIAL0 -> USB
+   -  SERIAL1 -> UART1 (DisplayPort)(DMA Enabled)
+   -  SERIAL2 -> UART2 (RC input) DMA-enabled
+   -  SERIAL3 -> UART3 (USER) DMA-enabled
+   -  SERIAL4 -> UART4 (GPS) DMA-enabled
+   -  SERIAL6 -> UART6 (USER)
+   -  SERIAL7 -> UART7 (USER)
+   -  SERIAL8 -> UART8 (ESC Telemetry)
+
+RC Input
+========
+RC input is configured on the R2 (UART2_RX) pin. It supports all RC protocols except PPM. See :ref:`common-rc-systems` for details for a specific RC system. :ref:`SERIAL2_PROTOCOL<SERIAL2_PROTOCOL>` is set to "23", by default, to enable this.
+
+- FPort requires connection to T2 and :ref:`SERIAL2_OPTIONS<SERIAL2_OPTIONS>` be set to "7".
+
+- CRSF also requires a T2 connection, in addition to R2, and automatically provides telemetry. Set :ref:`SERIAL2_OPTIONS<SERIAL2_OPTIONS>` to "0".
+
+- SRXL2 requires a connecton to T2 and automatically provides telemetry.  Set :ref:`SERIAL2_OPTIONS<SERIAL2_OPTIONS>` to "4".
+
+Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM. See :ref:`common-rc-systems` for details.
+
+OSD Support
+===========
+
+The autopilot  supports OSD using :ref:`OSD_TYPE<OSD_TYPE>` 1 (MAX7456 driver). The defaults are also setup to allow DJI Goggle OSD support on UART4. Both the internal analog OSD and the DisplayPort OSD can be used simultaneously by setting :ref:`OSD_TYPE2<OSD_TYPE2>` = 5
+
+
+PWM Output
+==========
+The BLITZ H743 Pro has 13 PWM outputs. The first 8 outputs support bi-directional DShot and DShot, as well as all PWM types. Outputs 9-10 support DShot, as well as all PWM types and outputs 11-12 only support PWM. Output 13 is pre-configured for serial LED.
+
+The PWM are in in five groups:
+
+
+* PWM 1-2 in group1
+* PWM 3-6 in group2
+* PWM 7-10 in group3
+* PWM 11-12 in group4
+* PWM 13 in group5
+
+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.
+
+.. note:: for users migrating from BetaflightX quads, the first four outputs M1-M4 have been configured for use with existing motor wiring using these default parameters:
+
+- :ref:`FRAME_CLASS<FRAME_CLASS>` = 1 (Quad)
+- :ref:`FRAME_TYPE<FRAME_TYPE>` = 12 (BetaFlightX) 
+
+Video Power Control
+===================
+
+The 12V video power can be turned off/on  using GPIO 81 which is already assigned by default to RELAY2.  This relay can be controlled either from the GCS or using a transmitter channel (See :ref:`common-auxiliary-functions`)
+
+RSSI Input
+==========
+
+The analog airspeed pin is "4" and is marked "RSSI" on the expansion board.
+
+Battery Monitoring
+==================
+
+The board has a built-in voltage sensor and  external current sensor. The voltage sensor can handle up to 8S
+LiPo batteries.
+
+The correct battery setting parameters are:
+
+
+* BATT_MONITOR 4
+* BATT_VOLT_PIN 10
+* BATT_VOLT_MULT 11
+* BATT_CURR_PIN 11
+* BATT_CURR_MULT 50
+
+These are set by default in the firmware and shouldn't need to be adjusted
+
+Compass
+=======
+
+The BLITZ Wing H743 does not have a builtin compass, but you can attach an external compass to I2C pins.
+
+
+Firmware
+========
+
+Firmware for these boards can be found `here <https://firmware.ardupilot.org>`_ in  sub-folders labeled "BlitzH74Pro".
+
+Loading Firmware
+================
+
+Initial firmware load can be done with DFU by plugging in USB with the
+bootloader button pressed. Then you should load the "with_bl.hex"
+firmware, using your favourite DFU loading tool.
+
+Once the initial firmware is loaded you can update the firmware using
+any ArduPilot ground station software. Later updates should be done with the
+\*.apj firmware files.
