# KakuteH7 Flight Controller
|
||
|
|
||
|
The KakuteH7 is a flight controller produced by [Holybro](http://www.holybro.com/).
|
||
|
|
||
|
## Features
|
||
|
|
||
|
- STM32H743 microcontroller
|
||
|

|
||
|
- BMP280 barometer
|
||
|
- microSD card slot
|
||
|
- AT7456E OSD
|
||
|
- 6 UARTs
|
||
|
- 9 PWM outputs
|
||
|
|
||
|

|

|
|
||
|
## 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 -> UART1 (Telem1)
|
||
|
- SERIAL2 -> UART2 (Telem2)
|
||
|
- SERIAL3 -> UART3 (GPS)
|
||
|
- SERIAL4 -> UART4
|
||
|
- SERIAL5 -> not available
|
||
|
- SERIAL6 -> UART6
|
||
|
- SERIAL7 -> UART7
|
||
|
- SERIAL7 -> USB2
|
||
|
|
||
|
## 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.
|
||
|
|
||
|
## FrSky Telemetry
|
||
|
|
||
|
FrSky Telemetry is supported using the T6 pin (UART6 transmit). You need to set the following parameters to enable support for FrSky S.PORT
|
||
|
|
||
|
- SERIAL6_PROTOCOL 10
|
||
|
- SERIAL6_OPTIONS 7
|
||
|
|
||
|
## OSD Support
|
||
|
|
||
|
The KakuteH7 supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
||
|
|
||
|
## PWM Output
|
||
|
|
||
|
The KakuteH7 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 builting 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 KakuteH7 does not have a builting 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.
