+# Skystars H7 Flight Controller
+
+The Skystars H7 is a flight controller produced by [Skystars](http://www.skystars-rc.com/).
+
+## Features
+
+ - STM32H743 microcontroller
+ - BMI270 IMU
+ - BMP280 barometer
+ - AT7456E OSD
+ - 6 UARTs
+ - 9 PWM outputs
+
+## Pinout
+
+![Skystars H7HD Board](SkystarsH7HD.jpg.jpg "Skystars H7HD")
+
+## UART Mapping
+
+The UARTs are marked RX and TX in the above pinouts. The RX pin is the
+receive pin for UARTn. The TX pin is the transmit pin for UARTn.
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> UART1 (Telem1)
+ - SERIAL2 -> UART2 (Telem2)
+ - SERIAL3 -> UART3 (GPS)
+ - SERIAL4 -> UART4
+ - SERIAL5 -> not available
+ - SERIAL6 -> UART6
+ - SERIAL7 -> UART7
+
+## 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 Skystars H7 supports OSD using OSD_TYPE 1 (MAX7456 driver).
+
+## PWM Output
+
+The Skystars H7 supports up to 9 PWM outputs. The pads for motor output
+M1 to M8 on the two motor connectors, plus M9 for LED strip or another
+PWM output.
+
+The PWM is in 5 groups:
+
+ - PWM 1, 2 in group1
+ - PWM 3, 4 in group2
+ - PWM 5, 6 in group3
+ - PWM 7, 8 in group4
+ - PWM 9 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.
+
+## Battery Monitoring
+
+The board has a builtin voltage and current sensor. The current
+sensor can read up to 130 Amps. The voltage sensor can handle up to 6S
+LiPo batteries.
+
+The correct battery setting parameters are:
+
+ - BATT_MONITOR 4
+ - BATT_VOLT_PIN 10
+ - BATT_CURR_PIN 11
+ - BATT_VOLT_MULT 10.1
+ - BATT_AMP_PERVLT 17.0
+
+## Compass
+
+The Skystars H7 does not have a builtin compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+## 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.
