  • The KK 2.1.5 is an extremely powerful and robust flight controller.
  • It has various multi-rotor craft types pre-installed to simply choose from.
  • Onboard firmware and LCD screen make it extremely easy to setup using easy to follow on-screen prompts and 4 buttons to navigate through the menus.
  • It is integrated with a 6 pin AVR interface.
  • It runs on an Atmega644 PA processor chip and needs a supply voltage of 4.8V-6.0V.
  • The KK 2.1.5 flight controller uses a signal of 1520us to control the ESCs.

KK 2.1.5 Multi-Rotor LCD Flight Control Board

The KK2.1.5 Multi-Rotor controller manages the flight of (mostly) multi-rotor Aircraft (Tricopters, Quadcopters, Hexacopters, etc). Its purpose is to stabilize the aircraft during flight and to do this, it takes signals from onboard gyroscopes (roll, pitch, and yaw) and passes these signals to the Atmega324PA processor, which in turn processes signals according to the user's selected firmware (e.g. Quadcopter) and passes the control signals to the installed Electronic Speed Controllers (ESCs) and the combination of these signals instructs the ESCs to make fine adjustments to the motors rotational speeds which in-turn stabilizes the craft. The HobbyKing KK2.1 Multi-Rotor control board also uses signals from your radio system via a receiver (Rx) and passes these signals together with stabilization signals to the Atmega324PA IC via the aileron; elevator; throttle and rudder user demand inputs. Once processed, this information is sent to the ESCs which in turn adjust the rotational speed of each motor to control flight orientation (up, down, backward, forwards, left, right). 

The KK2.1.5 was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts. The KK gyro system has been updated to an incredibly sensitive MPU 6050 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 the ATMEL Mega 644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional header has been added for voltage detection, so now there is no need for onboard soldering. A handy piezo buzzer is also included with the board for audio warning when activating and deactivating the board, which can be supplemented with an LED for visual signaling.

 If you’re new to multi-rotor flight or have been unsure about how to set up 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. A host of multi-rotor craft types are pre-installed on the kk2.1.5. Simply select your aircraft type, select the motor layout and propeller direction, calibrate your ESCs and radio and you’re ready to go! All of this is done with the help of easy-to-follow on-screen prompts!
