KK2.1.5 Flight Controller

The KK2.1.5 flight controller is next big evolution of the first generation KK flight control boards. The KK2.1.5 flight controller was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts.

The LCD screen and built in software makes install and setup easier than ever. A host of multi-rotor craft types are pre-installed, simply select your craft type, check motor layout/propeller direction, calibrate your ESCs and radio and you’re ready to go! All of which is done with easy to follow on screen prompts.

The KK gyro system has been updated to an incredibly sensitive 6050 MPU system making this the most stable KK board ever and allowing for the addition of an auto-level function. At the heart of the KK 2.1.5 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory.

The KK2.1.5 added polarity protection to the voltage sense header and a fuse protected buzzer outputs, in case something is accidentally plugged in incorrectly. The voltage sense line has been updated for better accuracy.

The board is clearly labeled and the voltage sense line color has been changed to red for easy identification, making installation and connections a snap.
