+Pinouts

+
+UART Defaults
+=============
+
+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)
+-    SERIAL2 -> USART2 (RX only,ESC Telemetry)
+-    SERIAL3 -> USART3 (DJI, DMA Enabled)
+-    SERIAL4 -> UART4 (SBUS pin is inverted and connects to RX pin)(TX DMA Enabled) For normal UART use, :ref:`BRD_ALT_CONFIG<BRD_ALT_CONFIG>` = 1.
+-    SERIAL5 -> UART5 (RX5 is fed from an inverter connected to DJI connector's SBUS pin, no TX pin)
+-    SERIAL6 -> UART6 (RC serial input, DMA-enabled)
+
+RC Input
+========
+
+RC input is configured on the SBUS pin which is inverted and feeds the R4 (UART4_RX) pin for most RC unidirectional protocols, including PPM.
+
+For CRSF/ELRS/SRXL2 connection of those to UART6 is pre-configured.
+
+The DJI connector' SBUS input can be used for SBUS only, but :ref:`SERIAL5_PROTOCOL<SERIAL5_PROTOCOL>` must be set to "23" and :ref:`SERIAL6_PROTOCOL<SERIAL6_PROTOCOL>` must be changed to something other than "23".
+
+Dshot capability
+================
+
+The FlywooF405 Pro supports up to 9 PWM outputs. The M1 to M4 outputs are on the esc connector and are bi-directional DShot capable, M5 to M8 on solder pads and DShot capable, plus LED pad(PWM output 9) for LED strip or another PWM output.
+
+The PWM is in 3 groups:
+
+-  PWM 1-2,5,7 in group1
+-  PWM 3-4 in group2
+-  PWM 6,8 in group2
+-  PWM 9   in group3
+
+Channels within the same group need to use the same output protocol. If any channel in a group uses DShot then all channels in the group need to use DShot. Channels 1-4 also support bi-directional DShot.
+
+GPIOs
+=====
+
+The FlywooF405 Pro outputs can be used as GPIOs (relays, buttons, RPM etc). To use them you need to set the output's ``SERVOx_FUNCTION`` to -1. See :ref:`common-gpios` page for more information.
+
+The numbering of the GPIOs for PIN variables in ArduPilot is:
+
+ - PWM1 50
+ - PWM2 51
+ - PWM3 52
+ - PWM4 53
+ - PWM5 54
+ - PWM6 55
+ - PWM7 56
+ - PWM8 57
+ - PWM9 58
+
+RSSI/Analog Airspeed Input
+==========================
+
+An analog input is provided and its reference pin number is "10"
+
+OSD Support
+===========
+
+The FlywooF405 Pro has an on-board OSD using :ref:`OSD_TYPE<OSD_TYPE>` =  1 (MAX7456 driver). The CAM and VTX pins provide connections for using the internal OSD.
+
+DJI Video and OSD
+=================
+
+A JST-GH-6P connector supports a standard DJI HD VTX connection and SERIAL3 is already setup for this by default.  Pin 1 of the connector is 10v so be careful not to connect this to any peripheral requiring 5v.
+
+Battery Monitoring
+==================
+
+The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input. The voltage sensor can handle up to 6S LiPo batteries.
+
+The default battery parameters are:
+
+-    :ref:`BATT_MONITOR<BATT_MONITOR>` = 4
+-    :ref:`BATT_VOLT_PIN<BATT_VOLT_PIN>` = 13
+-    :ref:`BATT_CURR_PIN<BATT_CURR_PIN>` = 12
+-    :ref:`BATT_VOLT_MULT<BATT_VOLT_MULT>` = 11.0
+-    :ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT>` = 58.8 (will need to be adjusted for whichever current sensor is attached)
+
+Compass
+=======
+
+The FlywooF405 Pro does not have a builtin compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+
+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 "FlywooF405Pro". Firmware is provided only for Copter/Heli but may be built for other vehicles using the `ArduPlot Custom Firmware Build Server <https://custom.ardupilot.org>`__
