+# KakuteH7-Wing Flight Controller
+
+The KakuteH7-Wing is a flight controller produced by [Holybro](http://www.holybro.com/).
+
+## Features
+    Processor
+        STM32H743 32-bit processor
+        AT7456E OSD
+    Sensors
+        ICM42688 Acc/Gyro
+        BMP280 barometer
+    Power
+        2S - 8S Lipo input voltage with voltage monitoring
+        9V/12V, 1.5A BEC for powering Video Transmitter
+        6V/7.2V, ?A BEC for servos
+        3.3V, 1A BEC
+    Interfaces
+        14x PWM outputs DShot capable, 4 outputs BiDirDShot capable
+        1x RC input
+        6x UARTs/serial for GPS and other peripherals
+        2x I2C ports for external compass, airspeed, etc.
+        USB-C port
+        Switchable 9V/12V VTX power
+        2 Switchable Camera inputs
+        All UARTS support hardware inversion. SBUS, SmartPort, and other inverted protocols work on any UART without “uninvert hack”
+        Input for second battery monitor
+
+## Pinout
+
+![KakuteH7-Wing Board](KakuteH7-Wing-pinout.jpg "KakuteH7-Wing)
+
+## 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.
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> UART7 (TELEM1) with CTS/RTS DMA Enabled
+ - SERIAL2 -> UART2 (Telem2) DMA Enabled
+ - SERIAL3 -> UART1 (GPS) DMA Enabled
+ - SERIAL4 -> USART3 (GPS2)
+ - SERIAL5 -> UART5 (User) DMA Enabled
+ - SERIAL6 -> USART6 (RX normally RCIN, BRD_ALT_CONFIG =1 for normal UART RX)
+ - SERIAL7 -> UART8 (User) DMA Enabled
+
+## RC Input
+
+RC input is configured on the R6 (UART6_RX) pin. It supports all RC
+protocols. For protocols requiring half-duplex serial to transmit
+telemetry (such as FPort) you should set BRD_ALT_CONFIG=1 and setup
+SERIAL6 as an RC input serial port, with half-duplex, pin-swap
+and inversion enabled.
+   
+## OSD Support
+
+The KakuteH7 supports OSD using OSD_TYPE 1 (MAX7456 driver).
+
+## PWM Output
+
+The KakuteH7 supports up to 14 PWM outputs. Outputs 1-10 support DShot. Outputs 5-8 support BiDirDshot.
+
+The PWM is in 5 groups:
+
+ - PWM 1-4 in group1
+ - PWM 5,6 in group2
+ - PWM 7,8 in group3
+ - PWM 9,10 in group4
+ - PWM 11-13 in group5
+ - PWM 14 in group6
+
+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.
+
+## Battery Monitoring
+
+The board has a builting voltage and current sensor. The current
+sensor can read up to ?? Amps. The voltage sensor can handle up to 6S
+LiPo batteries.
+
+The correct battery setting parameters are:
+
+ - BATT_MONITOR 4
+ - BATT_VOLT_PIN 8
+ - BATT_CURR_PIN 4
+ - BATT_VOLT_MULT 18.18
+ - BATT_AMP_PERVLT 36.6
+ 
+## Switchable Vidoe Supply and Camera Inputs
+
+The camera input defaults to CAM1 but can be switched to CAM2 by setting a relay set to pin 81. Both cameras should be the same video format.
+
+The 9V/12V video supply can be switched off (default is on) using a relay set topin 82.
+
+## Compass
+
+The KakuteH7-Wing does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+
+## Loading Firmware
+Firmware for these boards can be found at https://firmware.ardupilot.org in sub-folders labeled “KakuteH7-Wing”.
+
+Initial firmware load can be done with DFU by plugging in USB with the
+boot button pressed. Then you should load the "KakuteH7-Wing_bl.hex"
+firmware, using your favourite DFU loading tool.
+
+Subsequently, you can update firmware with Mission Planner.
