+
+.. note::
+
+	Due to flash memory limitations, this board does not include all ArduPilot features.
+        See :ref:`Firmware Limitations <common-limited_firmware>` for details.
+
+.. warning:: this firmware only applies to the F405 variant of the autopilot.

+
+
+Default UART order
+==================
+
+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.
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> USART1 (GPS) (DMA capable)
+ - SERIAL3 -> UART3 (Internally connected to ELRS module)
+ - SERIAL4 -> UART4 (DJI)
+ - SERIAL6 -> UART6 (RX pin only USER/SBUS alternate) (via inverter from SBUS pin, DMA capable) 
+
+Serial protocols shown are defaults, but can be adjusted to personal preferences.
+
+Servo/Motor Outputs
+===================
+
+Internally connected to integrated 4in1 ESC with BlueJay firmware. Bi-Directional DShot capable and are configured as such by default.
+
+RC Input
+========
+
+UART3 is tied internally to a 2.4GHz ELRS receiver module and defaulted to that protocol.
+
+There is a pin provided for SBUS input also, but the :ref:`SERIAL3_PROTOCOL<SERIAL3_PROTOCOL>` would have to be changed to something other than "23", and the :ref:`SERIAL6_PROTOCOL<SERIAL6_PROTOCOL>` set to "23", instead.
+
+.. note:: UART1 is configured by default for GPS but can be re-tasked for RC input for CRSF.etc. by changing its :ref:`SERIAL1_PROTOCOL<SERIAL1_PROTOCOL>` to "23". You can also have more than one receiver in the system at a time (usually used for long range hand-offs to a remote TX). See :ref:`common-multiple-rx` for details.
+
+Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM (SBUS requires external inversion on other UARTs). See :ref:`common-rc-systems` for details.
+
+OSD Support
+===========
+
+The BETAFPV F4 1S 12A AIO V3  supports DJI HD air units with telemetry using UART4 RX/TX. See :ref:`common-msp-osd-overview-4.2` for more info.
+
+
+Battery Monitor Configuration
+=============================
+These settings are set as defaults when the firmware is loaded (except :ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT>` which needs to be changed from the default value). However, if they are ever lost, you can manually set the parameters:
+
+Enable Battery monitor.
+
+:ref:`BATT_MONITOR<BATT_MONITOR>` =4
+
+Then reboot.
+
+:ref:`BATT_VOLT_PIN<BATT_VOLT_PIN>` 12
+
+:ref:`BATT_CURR_PIN<BATT_CURR_PIN>` 11
+
+:ref:`BATT_VOLT_MULT<BATT_VOLT_MULT>` 11.0
+
+:ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT>` 70.8
+
+Connecting a GPS/Compass module
+===============================
+
+This board does not include a GPS so an :ref:`external GPS <common-positioning-landing-page>` can be connected to allow operation of position holding/tracking modes (ie LOITER,etc.).
+
+.. warning:: since a compass cannot be attached, yaw information can only be determined with a GPS attached and using ArduPilot's internal GSF yaw estimator. This yaw estimator is particularly sensitive to vibration and could result in erratic operation, or even a crash, if vibration is moderate or severe. Therefore, using positioning modes is not recommended.
+
+Firmware
+========
+This board does not come with ArduPilot firmware pre-installed. Use instructions here to load ARduPilot the first time :ref:`common-loading-firmware-onto-chibios-only-boards`.
+
+Firmware for this board can be found `here <https://firmware.ardupilot.org>`_ in  sub-folders labeled
+"BETAFPV-F405".
