Holybro Kakute H7 Flight Controller – Overview & Technical Details
The Holybro Kakute H7 is a modern and high-performance flight controller that combines a wide range of professional features. It offers integrated Bluetooth, an HD camera port, barometer, OSD, 6 UART interfaces, a large MicroSD Blackbox slot, as well as reliable 5V and 9V BECs. Performance, stability, and user-friendliness have been significantly improved compared to the previous F7 generation.
With the integrated Bluetooth module (depending on model), the Kakute H7 can be conveniently configured via the SpeedyBee App for iOS and Android. A version without Bluetooth is also available.
The flight controller is fully DJI HD compatible and includes a dedicated 9V output to reliably power HD VTX systems such as the DJI/Caddx Air Unit or Caddx Vista. Analog FPV systems are supported as well.
With its 6 UART ports, two 4-in-1 ESC connectors for easy X8 configurations, an integrated barometer, LED and buzzer pads, as well as I2C connections for GPS and magnetometers, the Kakute H7 is extremely versatile and an excellent choice for FPV pilots and professional applications alike.
