# KakuteH7 v2 Flight Controller
|
||
|
|
|
||
|
|
The KakuteH7 v2 is a flight controller produced by [Holybro](http://www.holybro.com/).
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|

|
||
|
|
- BMI270 IMU
|
||
|
|
- BMP280 barometer
|
||
|
|
- Onboard Flash: 1GBit
|
||
|
|
- AT7456E OSD
|
||
|
|
- 6 UARTs
|
||
|
|
- 9 PWM outputs
|
||
|
|
|
||
|
|
## 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.
|
||
|
|
|
||
|
|
- SERIAL0 -> USB
|
||
|
|
- SERIAL1 -> UART1 (DJI-RX, DMA-enabled)
|
||
|
|
- SERIAL2 -> UART2 (Telem2, DMA-enabled) (connected to internal BT module)
|
||
|
|
- SERIAL3 -> UART3 (VTX)
|
||
|
|
- SERIAL4 -> UART4 (GPS, DMA-enabled)
|
||
|
|
- SERIAL5 -> not available
|
||
|
|
- SERIAL6 -> UART6 (RX, DMA-enabled)
|
||
|
|
- SERIAL7 -> UART7 (ESC Telemetry)
|
||
|
|
|
||
|
|
## RC Input
|
||
|
|
|
||
|
|
RC input is configured on the R6 (UART6_RX) pin. It supports all RC
|
||
|
|
protocols except PPM. For protocols requiring half-duplex serial to transmit
|
||
|
|
telemetry (such as FPort) you should configure SERIAL6 with half-duplex, pin-swap
|
||
|
|
and inversion enabled.
|
||
|
|
|
||
|
|
## FrSky Telemetry
|
||
|
|
|
||
|
|
FrSky Telemetry is supported using the Tx pin of any UART including SERIAL6/UART6 . You need to set the following parameters to enable support for FrSky S.PORT (example shows SERIAL6).
|
||
|
|
|
||
|
|
- SERIAL6_PROTOCOL 10
|
||
|
|
- SERIAL6_OPTIONS 7
|
||
|
|
|
||
|
|
## OSD Support
|
||
|
|
|
||
|
|
The KakuteH7 v2 supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
||
|
|
|
||
|
|
## VTX Support
|
||
|
|
|
||
|
|
The JST-GH-6P connector supports a standard DJI HD VTX connection. Pin 1 of the connector is 9v so be careful not to connect
|
||
|
|
this to a peripheral requiring 5v. The 9v supply is controlled by RELAY_PIN2 and is on by default. It can be configured to be operated by an RC switch by selecting the function RELAY2.
|
||
|
|
|
||
|
|
## 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. Channels 1-8 support bi-directional 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 KakuteH7 v2 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.
