Holybro Kakute H7 Mini

Holybro Kakute H7 Mini

Holybro Kakute H7 Mini is a packed flight controller. First of all, it includes an onboard VTX ON/OFF Pit Switch with battery voltage readout. Moreover, it comes with HD System/VTX ports and a 4in1 ESC plug. Besides, it carries a barometer, OSD, six UARTs, and a simple soldering layout.

The Kakute H7 Mini improves on its F7 predecessor. Specifically, it upgrades hardware parts and board layout. In addition, this board supports HD video systems. You can plug in HD units such as Caddx Vista directly. Meanwhile, it also works with analog FPV systems.
Furthermore, its onboard VTX ON/OFF Pit Switch lets you cut VTX power via your RC transmitter. For example, use this feature during drone setup or GPS wait times. It also helps before races. In turn, you avoid VTX overheating and radio interference with nearby pilots.

It offers six dedicated UART ports with built-in signal inversion for peripherals. Plus, it has a 4in1 ESC plug and M5-M8 compatible x8 signal pads. Therefore, it supports octocopter builds easily.
What’s more, the integrated BetaFlight OSD shows key data on your FPV screen. You can view battery voltage, flight time, warnings, RSSI and Smart Audio data.
On top of that, the onboard barometer prepares the board for autonomous flight. Lastly, LED, buzzer and I2C (SDA & SCL) pads accept external GPS and magnetometer modules.
