Holybro Kakute H7 V1.3 flight controller for drones and opto-copers

Holybro Kakute H7 V1.3

The newly launched Holybro Kakute H7 V1.3 flight controller helps 2 to 8S LIPO batteries and is meant for traditional four-motor drones {and professional} octocopters. It has 9 PWM outputs (2x4in1ESC and LED), six UART ports (UART2 is used for Bluetooth telemetry), and a devoted HD digital port for DJI O3 Air Unit and different suitable VTXs.

In response to HolyBro, the Kakute H7 incorporates the perfect options of its F7 predecessor and additional improves on {hardware} elements and structure. With the extra built-in Bluetooth chip onboard, you may carry out Betaflight configuration and tune wirelessly in your telephone with the SpeedyBee Android & IOS App. The built-in 5V 2A and 9V 3A BECs can energy numerous equipment, together with high-power VTXs and cameras. Moreover, it has a MicroSD Card slot for nearly limitless Blackbox knowledge logging.

The built-in BetaFlight OSD makes it straightforward to show essential info in your FPV show, like battery voltage, flight time, warnings, RSSI, good audio options, and extra. Additionally it is prepared for autonomous flight with the onboard barometer. There are LED & buzzer pads, I2C pads (SDA & SCL) for exterior GPS/Magnetometers.
