+# iFlight BLITZ Wing H743 Flight Controller
+
+The BLITZ Wing H743 is a flight controller produced by [iFlight](https://shop.iflight.com/electronics-cat27/BLITZ-Wing-H743-Flight-Controller-Pro2174).
+
+## Features
+
+ - MCU - STM32H743 32-bit processor running at 480 MHz
+ - Gyro: ICM42688
+ - SDCard for logging
+ - 5V 3A BEC for Flight Controller
+ - 9V 3A BEC for VTX
+ - 5-8.4V 6A BEC for Servo
+ - Barometer: DPS310
+ - OSD: AT7456E
+ - 7x UARTs
+ - 13x PWM Outputs (12 Motor Output, 1 LED)
+ - Battery input voltage: 2S-8S
+ - 2x I2C for external compass, airspeed, etc.
+ - CAN port
+
+## Physical
+ - Mount pattern: 30.5*30.5mm/?4
+ - Dimensions: 36.9*52mm
+ - Weight: 35g
+
+## Pinout

+
+## 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.
+|Name|Pin|Function|
+|:-|:-|:-|
+|SERIAL0|COMPUTER|USB|
+|SERIAL1|RX1/TX1|UART1 (DJI connector, DMA-enabled)|
+|SERIAL2|TX2/RX2|UART2 (RX, DMA-enabled)|
+|SERIAL3|TX3/RX3|UART3 (DMA-enabled)|
+|SERIAL4|TX4/RX4|UART4 (GPS, DMA-enabled)|
+|SERIAL6|TX6/RX6|UART6|
+|SERIAL7|TX7/RX7|UART7|
+|SERIAL8|TX8/RX8|UART8 (ESC Telemetry)|
+
+## RC Input
+
+RC input is configured on the (UART2_RX/UART2_TX) pins which forms part of the DJI connector. It supports all serial RC protocols.
+
+## OSD Support
+
+The BLITZ Wing H743 supports OSD using OSD_TYPE 1 (MAX7456 driver). Simultaneously, DisplayPort HD OSD is enabled by default and available on the HD VTX connector.
+
+## PWM Output
+
+The BLITZ Wing H743 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.
+
+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.
+
+## Video Power Control
+
+The 9V 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`)
+
+## Analog Airspeed Input
+
+The analog airspeed pin is "4"
+
+## Battery Monitoring
+
+The board has a built-in voltage sensor and  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.
+
+## 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. Updates should be done with the
+*.apj firmware files.
