KK2.1.5 MULTI-ROTOR LCD FLIGHT CONTROL BOARD
D
ESCRIPTION
The next evolution of the rotor revolution is here!! The KK2.1.5 is packing new found power with updated
sensors, memory and header pins.
The KK2.1.5 is next big evolution of the first generation KK flight control boards. The KK2.1.5 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 original 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
KK2.1.5 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An
additional polarity protected header has been added for voltage detection, so no need for on-board
soldering. A handy piezo buzzer is also included for audio warning when activating and deactivating the
board.
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.
If you’re new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.1.5
was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be
quick and easy.
