+# MicoAir743-AIO Flight Controller
+
+The MicoAir743-AIO is a flight controller designed and produced by [MicoAir Tech](http://micoair.com/).
+
+## Features
+
+ - STM32H743 microcontroller
+ - BMI088/BMI270 dual IMUs
+ - DPS310 barometer
+ - 12V 2A BEC; 5V 2A BEC
+ - MicroSD Card Slot
+ - 7 UARTs
+ - Integrated 4-in-1 AM32 35A ESC, 5 additional PWM outputs, one defaulted as serial LED
+
+ - 1 I2C
+ - 1 SWD
+
+## Physical
+
+![MicoAir H743 AIO Physical Size](MicoAir743-AIO_Physical_Size.jpg)
+
+## UART Mapping
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
+ - SERIAL2 -> UART2 (DisplayPort, DMA-enabled)
+ - SERIAL3 -> UART3 (GPS, DMA-enabled)
+ - SERIAL4 -> UART4 (MAVLink2, DMA-enabled)
+ - SERIAL5 -> UART6 (RCIN, DMA-enabled)
+ - SERIAL6 -> UART7 (RX only, ESC Telemetry, DMA-enabled)
+ - SERIAL7 -> UART8 (User, DMA-enabled)
+
+## RC Input
+
+The default RC input is configured on the UART6. The SBus input on the HD VTX connector is tied to RX6.
+
+
+## VTX Support
+
+The SH1.0-6P connector supports a DJI Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v.
+
+## PWM Output
+
+The MicoAir743-AIO supports up to 9 PWM outputs.
+
+All the channels support DShot.
+
+Channels 1-8 support bi-directional DShot.
+
+PWM outputs are grouped and every group must use the same output protocol:
+
+1, 2, 3, 4 are Group 1;
+
+5, 6 are Group 2;
+
+7, 8, 9 are Group 3;
+
+PWM1-4 are internally tied to the 4-in-1 ESC. PWM 9 is labelled as LED output on the board.
+## Battery Monitoring
+
+The board has internal voltage sensor and current sensor for battery.
+The voltage input should be 3~6S LiPo batteries.
+
+The default battery parameters are:
+
+ - BATT_MONITOR 4
+ - BATT_VOLT_PIN 10
+ - BATT_CURR_PIN 11
+ - BATT_VOLT_MULT 21.2
+ - BATT_CURR_SCALE 14.14
+
+## Compass
+
+The MicoAir743-AIO does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
+
+## Mechanical
+
+ - Mounting: 25.5 x 25.5mm, Φ3mm
+ - Dimensions: 36 x 36 x 8 mm
+ - Weight: 10g
+
+## Ports Connector
+
+![MicoAir H743 AIO Ports Connection](MicoAir743-AIO_Ports_Connection.jpg)
+
+## 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 favorite 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.
