KK2.1.5 LCD Flight Control Board (Red Switch) The kk 2.1.5 flight controller is next big evolution of the first generation KK flight controller 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 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. Description: Size: 50.5mm x 50.5mm x 12mm Weight: 21 gram (Inc Piezo buzzer) IC: Atmega Gyro/Acc: InvenSense Inc. Auto-level: Yes Input Voltage: 4.8-6.0V AVR interface: standard 6 pin Signal from Receiver: 1520us (5 channels) Signal to ESC: 1520us Firmware Version: 1.5 Pre-installed firmware. Features: * The KK2.1.5 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 the ESCs to make fine adjustments to the motors rotational speed which in turn stabilizes your multi-rotor craft. * The KK2.1.5 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 the ESCs which in turn adjust the rotational speed of each motor to induce controlled flight (up, down, backwards, forwards, left, right, yaw). Package included: 1 x KK2.1.5 LCD Flight controller (Red Switch) 1 x set of connection wires 1 x buzzer
