KK 2.1 Multi-Rotor Control Board

User Guide

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 exclusively for HobbyKing by the grandfather of the KK revolution, Rolf R Bakke, the KK2.1 is

the next evolution of the first generation KK flight control boards and has been engineered from the

ground-up to bring multi-rotor flight to everyone, not just the experts. The LCD screen and built-in

software makes installation and set-up easier than ever.

The original KK gyro system has been updated to the incredibly sensitive 6050 MPU system making this

the most stable KK board ever and adds 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 on-board

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.

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!

If you’re 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.

Go ahead and get started.

Introduction The HobbyKing KK2.1 Multi-Rotor controller manages the flight of (mostly) multi-rotor Aircraft (Tricopters, Quadcopters, Hexcopters etc). Its purpose is to stabilize the aircraft during flight and to do this, it takes signals from on-board gyroscopes (roll, pitch and yaw) and passes these signals to the Atmega324PA processor, which in-turn processes signals according the users selected firmware (e.g.

Initial Set-Up STEP-1 Mount the FC on the frame with the LCD facing front and the buttons facing back. You can use the supplied antistatic foam container as a form of protective case for the Flight Controller on the craft. STEP-2 Connect the receiver outputs to the corresponding left-hand side of the controller board.

The completed Receiver and Motor wiring (for a QUAD Copter) looks like this: The Flight Controller Board must always have a source of +5v from an ESC, either one of the motors ESC or from a separate unit feeding the Receiver. If each ESC has a BEC (normal unless OPTO types) then it may be necessary to remove the power feed from the other ESC, usually by cutting the power line (RED) Cable on the other ESC.

Settings Self-Level Settings Camera Stab Settings Turn on the power and press the ‘Menu’ button, then using the Flight Controller, if any are reversed, then go to your Transmitter and reverse that channel.

Settings Self-Level Settings controlled, either by STICK or an AUX Channel. "STICK MODE": Self-levelling is turned on by holding the aileron to the right when arming or disarming. Turn it off with left aileron. "AUX": Self-levelling is turned on/off by the AUX Channel.

PI Editor “Mixer Editor”: Receiver Test “Channel”: Select the channel to be adjusted. Mode Settings "Throttle": Amount of throttle command. Usually 100% if the output Stick Scaling channel is connected to an ESC. Misc. Settings Self-Level Settings Camera Stab Settings "Aileron": Amount of aileron/roll command. Use positive value for motors on the right side of the roll axis and negative for the left side of the roll axis. The value is given by the motor's distance from the roll axis.

Tuning Guide 1: Make sure the KK2 reads the transmitter stick neutrals. Go to the "Receiver Test" menu and use the trims to get the values to zero. 2: Go to the "PI Editor" menu and set P to 150 and I to zero for both the Roll and Pitch Axis. It is only necessary to edit the roll axis, pitch axis will be automatically changed to the same values as the roll axis. Leave the P-limit and I-limit alone, it is seldom necessary to change them.
PAGE 12
You can also increase "Roll/Pitch/Yaw I Limit" for increased heading-hold "memory", that is how far it can deviate and still return to original attitude. Too large a ‘memory’ can cause problems if you have a "blow out" on one of the axis and the Flight Controller tries to correct it with opposite control input and then when the blow-out conditions disappear, the craft will try to return to an unknown attitude. It is recommended that unless you know what you are doing, to leave the limit values as default.

Mode Settings A negative value reverses servo direction. Adjust value until camera is Stick Scaling Misc. Settings Self-Level Settings steady. 1. The Gimbal Roll servo is connected to Motor-7 output. 2. The Gimbal Pitch servo is connected to Motor-8 output.

Accessing the Self-Levelling Mode 1. You can access the self-levelling mode either from the settings of STICK or AUX channel. 2. When set to AUX Mode you must connect a spare channel usually CH5 or Ch6 and changing the Transmitter switch position will enable/disable Self-Levelling mode. 3.
