|
|
|
|
The KakuteF7 AIO is a flight controller produced by [Holybro](http://www.holybro.com/product/59).
|
|
|
|
## Features
|
|
|
|
- STM32F745 microcontroller
|
|
- ICM20689 IMU
|
|
- BMP280 barometer
|
|
- microSD card slot
|
|
- AT7456E OSD
|
|
- 6 UARTs
|
|
- 6 PWM outputs
|
|
|
|
## Pinout
|
|
|
|
The KakuteF7 comes in two varients. One is an AIO (All-In-One) board,
|
|
with OSD. The other is a smaller board without OSD.
|
|
|

|
## 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 -> UART7
|
|
- SERIAL6 -> UART6 (Transmit only, FrSky)
|
|
|
|
The SERIAL5 port (UART7) is for ESC telemetry, and has a R7 pad on
|
|
each of the four corners of the KakuteF7 AIO board.
|
|
|
|
## RC Input
|
|
|
|
RC input is configured on the R6 (UART6_RX) pin. It supports all RC protocols.
|
|
|
|
## 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 KakuteF7 AIO supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
|
|
|
## PWM Output
|
|
|
|
The KakuteF7 supports up to 6 PWM outputs. The pads for motor output M1 to M6 on the above diagram are for the 6 outputs. All 6 outputs support DShot as well as all PWM types.
|
|
|
|
The PWM is in 3 groups:
|
|
|
|
- PWM 1, 2 and 3 in group1
|
|
- PWM 4 and 5 in group2
|
|
- PWM 6 in group3
|
|
|
|
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 13
|
|
- BATT_CURR_PIN 12
|
|
- BATT_VOLT_MULT 10.1
|
|
- BATT_AMP_PERVLT 17.0
|
|
|
|
## Compass
|
|
|
|
The KakuteF7 AIO 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.
