# KakuteH7Mini Flight Controller |
||||||
|
|
||||||
|
The KakuteH7Mini is a flight controller produced by [Holybro](http://www.holybro.com/). |
||||||
|
|
||||||
|
## Features |
||||||
|
|
||||||
|
- MCU - STM32H743 32-bit processor running at 480 MHz |
||||||
|

||||||
|
- Barometer - BMP280 |
||||||
|
- OSD - AT7456E |
||||||
|
- Onboard Flash: 128Mbits |
||||||
|
- 6x UARTs (1,2,3,4,6,7) |
||||||
|
- 9x PWM Outputs (8 Motor Output, 1 LED) |
||||||
|
- Battery input voltage: 2S-6S |
||||||
|
- BEC 5V 2A |
||||||
|
|
||||||
|
## 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 VTX, DMA-enabled) |
||||||
|
- SERIAL2 -> UART2 (VTX) |
||||||
|
- SERIAL3 -> UART3 (GPS, DMA-enabled) |
||||||
|
- SERIAL4 -> UART4 (DMA-enabled) |
||||||
|
- SERIAL5 -> not available |
||||||
|
- SERIAL6 -> UART6 (RX/SBUS, DMA-enabled) |
||||||
|
- SERIAL7 -> UART7 (ESC Telemetry) |
||||||
|
|
||||||
|
## RC Input |
||||||
|
|
||||||
|
RC input is configured on the R6 (UART6_RX) pin. It supports all serial RC |
||||||
|
protocols. For protocols requiring half-duplex serial to transmit |
||||||
|
telemetry (such as FPort) you should 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 KakuteH7Mini supports OSD using OSD_TYPE 1 (MAX7456 driver). |
||||||
|
|
||||||
|
## PWM Output |
||||||
|
|
||||||
|
The KakuteH7Mini supports up to 9 PWM outputs. The pads for motor output |
||||||
|
M1 to M4 on the motor connectors and M5 to M8 on separate pads, 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 1-4 support bi-directional 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 11.1 |
||||||
|
- BATT_AMP_PERVLT 59.5 |
||||||
|
|
||||||
|
## Compass |
||||||
|
|
||||||
|
The KakuteH7Mini 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. |
