Kk2.1.5 is a multi-rotor LCD Flight Control card with 6050mpu and Atmel 644PA. KK2.1.5 is designed to bring multi-rotor flying to everyone, not just experts.
The LCD display and built-in software make setup easier than ever. Numerous types of rotorcraft are pre-installed, just select your vehicle type, check the motor layout/propeller orientation, set up your ESCs and radio and you are ready to go! It's all easy to follow on the screen! The KK gyro system has been updated to an incredibly accurate 6050 MPU system, making this the most stable KK board yet and the addition of an auto-level function. The KK2.1.5 features an Atmel Mega644PA 8-bit AVR RISC-based microprocessor with 64k memory.
KK2.1.5 Multi-Rotor controller, flight control for multi-rotor aircraft card (Tricopters, Quadcopters, Hexcopters etc.). Its purpose is to stabilize the aircraft during flight. To do this the 6050MPU receives signals from the gyro/acc (roll, pitch and yaw) then transmits the signal to the Atmega644PA IC. The Atmega644PA IC unit then processes these signals according to the user-selected firmware and transmits the control signals to the installed Electronic Speed Controllers (ESCs).
KK2.1.5 Multi-Rotor control board also radio systems use signals from your receiver (Rx) and transmit these signals to the Atmega644PA IC via aileron, elevator, throttle and rudder inputs. After this information is processed, the IC sends various signals to the ESCs, which adjust the rotation speed of each motor, to initiate control flight (up, down, backward, forward, left, right).
An additional polarity-protected header has been added for voltage detection, so no onboard soldering is required. There's also a handy piezo buzzer to sound when activating and disabling the board. KK2.1.5 adds polarity protection to the voltage sensing head and fuse-protected audible warning outputs in case of accidental misconnection. Voltage detection pipeline updated for better accuracy. Assembly and connections are very easy. If you're new to multi-rotor flying or unsure of how to set up the KK board, KK2.1.5 is made for you. 6 Pin USBasp AVR programming interface ensures future software updates are quick and easy.
