Hobbyking KK2.0 Multi-rotor LCD Flight Control Board (US Warehouse)

Hobbyking KK2.0 Multi-rotor LCD Flight Control Board (US Warehouse)
Hobbyking KK2.0 Multi-rotor LCD Flight Control Board (US Warehouse)

Designed by the Grand father of the KK revolution, Rolf R Bakke, exclusively for HobbyKing, the KK2.0 is the evolution of the first generation KK flight control boards. The KK2.0 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 your ready to go! all of which is done with easy to follow on screen prompts!

The original KK gyro system has been updated to an incredibly sensitive dual chip 3 Axis gyro and single chip 3 axis accelerometer system making this the most stable KK board ever and allowing for the addition of an Auto-level function. At the heart of the KK2.0 is an Atmel Mega324PA 8-bit AVR RISC-based microcontroller with 32k of memory. An additional 2 motor output channels have been added to the KK2.0 allowing for a total of 8 motors to be controlled (Octocopter). A handy Piezo buzzer is also included with the board for audio warning when activating and deactivating the board.

If your new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.0 was built for you. The 6 Pin USBasp AVR Programming interface ensures future software updates will be quick and easy.

Whats is a Multi-Rotor Control board you ask?

The HobbyKing KK2.0 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 three on board gyros (roll, pitch and yaw) then passes the signal to the Atmega324PA IC. The Atmega324PA 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 HobbyKing KK2.0 Multi-Rotor control board also uses signals from your radio systems receiver (Rx) and passes these signals to the Atmega324PA IC via the ail, ele, thr and rud 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).

Note: A user manual is available under the files tab.
*Royalties paid on each unit sold to Rolf R Bakke, the original KK Designer.

Hi there :) I've just completed the build of a scratch-build quadcopter. And while I was configuring the KK2.1 flight controller, I though it might be helpfull for others to show what I did.. So here it is :)

This is the same KK2 board I used when I build my flying saucer (an inherently unstable platform) and when I increased the gains to get it to stabilize, it flew fantastic.

I just finished setting up my second one of these on a quad. I have tried 3 other flight control boards and this is by far the best. Very stable with auto level on and very agile with it turned off. The setup using the LCD display is the way to go. You can change settings in the field without having to connect to a computer. Download the flash program and purchase the USB adapter and upgrade to the 1.5 or 1.6 version of the flash. The instructions are in the files section as well as the programs. Also check out RCGroups forum for additional tips. I followed the tutorial and it's easy.

I purchased this unit for my dji f450. I did a fair amount of searching the web before I bought it. It was very easy to set up. I did have to tune it down a bit due to I'm a noob when it comes to multi rotors. I also have the f550 running the 3dr apm board. I like the kk2 better than the APm board. No flyaway and feels like I have control on the multi. It doesn't have all the cool stuff that the APM has but it's more reliable. I've shelved the f550. I don't trust it anymore. I fly the f450 with the kk2 almost every night. I don't think you will be discouraged if you are new and buy this board. It's a winner!!

I use this board for a multirotor, and also as a flight stabilizer, and camera stabilizer using OpenAero2. It has none of the GPS supported features, but aside from that, it is fantastic. I had high expectaions reading the reveiws, and once I figured out the details it has been a delight. I broke on board learning to fly my tricopter, but it was my fault. All that broke was the LCD screen because it took a direct hit. Even with the damaged LCD, it still worked just fine. There is a learning curve to making it work perfectly, but works reasonably well right out of the block. Be sure to upload the most current firmware, and it is even better.

This is a preliminary review. This FC is super cheap and super easy to install, now I just hope it performs well! I will post another review with The KK2.0s flight performance.

I have purchased 4 of these boards and never had a problem getting any of them to work properly. They are so simple to use that it is hard for me to consider using anything else. If you want a no hassle flight controller, get one of these. There are many other boards that have more flexibility than this one, but if you just need a solid controller to fly around with a camera, this is the one for you.
