The next evolution of the rotor revolution is here!! The KK2.1 is packing new found power with updated sensors, memory and header pins.

Designed by the grandfather of the KK revolution, Rolf R Bakke, exclusively for HobbyKing, the KK2.1 is the evolution of the first generation KK flight control boards. The KK2.1 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 yourESCs and radio and youre 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 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional header has been added for voltage detection, so no need for on-board soldering. A handy piezo buzzer is also included with the board for audio warning when activating and deactivating the board.

If youre new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.1 was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be quick and easy.

t(Custom Mix via the "Mixer Editor" option)

The Mixer Editor allows you to adjust where and how much signal the motors receive from stick input and sensors. This allows you to create any configuration possible with up to 8 motors or servos.

tWhat is a Multi-Rotor Control board you ask?

The KK2.1 Multi-Rotor controller is a flight control board for multi-rotor aircraft (Tricopters, Quadcopters, Hexcopters etc). Its purpose is to stabilize the aircraft during flight. To do this it takes the signal from the 6050MPU gyro/acc (roll, pitch and yaw) then passes the signal to the Atmega644PA IC. The Atmega644PA IC unit then processes these signals according the users selected firmware and passes control signals to the installed Electronic Speed Controllers (ESCs). These signals instruct theESCs to make fine adjustments to the motors rotational speed which in turn stabilizes your multi-rotor craft.

The KK2.1 Multi-Rotor control board also uses signals from your radio systems receiver (Rx) and passes these signals to the Atmega644PA IC via the aileron, elevator, throttle and rudder inputs. Once this information has been processed the IC will send varying signals to theESCs which in turn adjust the rotational speed of each motor to induce controlled flight (up, down, backwards, forwards, left, right, yaw).

** Note: An updated software version1.6 for the KK2.1 is available. It is always recommended to update to the latest software version as part of your initial setup.(this is different than v1.6 for 2.0)
