TOOGOO(R) KK 2.1 LCD Flight Control Board 1.9S Firmware for Multirotor Flying Wing V-tail Green
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 the ESCs to make fine adjustments to the motors rotational speed which in turn stabilizes your multi-rotor craft.
The KK2 Multi-Rotor control board also uses signals from your radio systems receiver (Rx) and passes these signals to the Atmega 644PA IC via the aileron, elevator, throttle and rudder inputs.
Once this information has been processed the IC will send varying signals to the ESCs which in turn adjust the rotational speed of each motor to induce controlled flight (up, down, backwards, forwards, left, right, yaw).
At the heart of the KK2 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.

• Generation KK2.1 board with updated sensors, memory, header pins, and hard case protection..
• The board comes with software version V1.9S for easy setup..
• The KK2 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..
• The KK2 is next big evolution of the first generation KK flight control boards. The KK2 was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts..
