+
+Default UART order
+==================
+
+- SERIAL0 = console = USB
+- SERIAL1 = UART4 (MAVLink2)
+- SERIAL2 = USART1 (MAVLink2, DMA capable)
+- SERIAL3 = UART5 (GPS)
+- SERIAL4 = USART3 (GPS, TX3 DMA capable)
+- SERIAL5 = USART6 ((User, TX3 DMA capable)
+- SERIAL6 = USART2 (RCinput on RX2, to use as normal UART input use :ref:`BRD_ALT_CONFIG<BRD_ALT_CONFIG>` = 1)
+
+Serial protocols shown are defaults, but can be adjusted to personal preferences.
+
+OSD Support
+===========
+The CSKY405 supports using its internal OSD using OSD_TYPE 1 (MAX7456 driver). External OSD support such as DJI or DisplayPort can be supported using USART6 or any other free UART. See :ref:`common-msp-osd-overview-4.2` for more info.
+
+PWM Outputs
+===========
+
+The CSKY405 supports up to 10 PWM outputs. All outputs support DShot.
+
+The PWM is in 5 groups:
+
+ - PWM 1 in group1
+ - PWM 2 in group2
+ - PWM 3,4 in group3
+ - PWM 5,6,10 in group4
+ - PWM 7 in group5
+ - PWM 8,9 in group6
+
+RC Input
+========
+
+RC input is configured on the RX2 pin. It supports all single wire RC
+protocols except bi-directional serial protocols such as CRSF, ELRS, etc. Instead, these devices can be connected using both TX2 and RX2 if if :ref:`BRD_ALT_CONFIG<BRD_ALT_CONFIG>` = 1 and :ref:`SERIAL6_PROTOCOL<SERIAL6_PROTOCOL>` set to "23".
+
+- PPM is not supported.
+
+- DSM/SRXL connects to the RX2  pin.
+
+- FPort requires connection to TX2 and RX2 via a bi-directional inverter. See :ref:`common-FPort-receivers`.
+
+- CRSF also requires a TX2 connection, in addition to RX2, and automatically provides telemetry. Set :ref:`SERIAL6_PROTOCOL<SERIAL6_PROTOCOL>` to "23"
+
+- SRXL2 requires a connection to TX2 and automatically provides telemetry.  Set :ref:`SERIAL6_OPTIONS<SERIAL6_OPTIONS>` to "4" and :ref:`SERIAL6_PROTOCOL<SERIAL6_PROTOCOL>` set "23".
+
+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:
+
+Enimages/CSKY405_wiring.pngable Battery monitor.
+
+- :ref:`BATT_MONITOR<BATT_MONITOR>` =4
+
+Then reboot.
+
+- :ref:`BATT_VOLT_PIN<BATT_VOLT_PIN>` 14
+- :ref:`BATT_CURR_PIN<BATT_CURR_PIN>` 7
+- :ref:`BATT_VOLT_MULT<BATT_VOLT_MULT>` 21
+- :ref:`BATT_AMP_PERVLT<BATT_AMP_PERVLT>` 10.35
+
+VTX power control
+=================
+
+GPIO 84 controls the VTX BEC output to pins marked "12V". Setting this GPIO high using an :ref:`common-auxiliary-functions` or :ref:`common-relay` removes voltage supply to pins.
+
+Connecting a GPS/Compass module
+===============================
+
+This board does not include a GPS or compass so an :ref:`external GPS/compass <common-positioning-landing-page>` should be connected as shown below in order for autonomous modes to function.
+
+Firmware
+========
+
+Firmware for this board can be found `here <https://firmware.ardupilot.org>`_ in  sub-folders labeled
+"CSKYF405".
+
+Loading Firmware
+================
+Firmware for these boards can be found at https://firmware.ardupilot.org in sub-folders labeled CSKY405.
+
+Initial firmware load can be done with DFU by plugging in USB with the
+boot button pressed. Then you should load the "CSKY405_bl.hex"
+firmware, using your favorite DFU loading tool.
+
+Subsequently, you can update firmware with Mission Planner.
