Overview

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 by the grandfather of the KK revolution, Rolf R Bakke, exclusively for HobbyKing, the KK2.1 is the evolution of the first generation KK flight control boards. The KK2.1 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 original KK gyro system has been updated to an incredibly sensitive 6050 MPU 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 an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional header has been added for voltage detection, so 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.

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.

(Custom Mix via the "Mixer Editor" option)

The Mixer Editor allows you to adjust where and how much signal the motors receive from stick input and sensors. This allows you to create any configuration possible with up to 8 motors or servos.

What is a Multi-Rotor Control board you ask?

The HobbyKing KK2.1 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 HobbyKing KK2.1 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).

** Note: An updated software version”1.6” for the KK2.1 is available. It is all ways recommended to update to the latest software version as part of your initial setup.(this is different than v1.6 for 2.0)

Haven't had a try of this yet but have heard that they are pretty damn good.

I only bought this because there was a sale on and I'm only writing this review because I want the extra points before HobbyKing removes it from my review list : )
Ok, let's not beat around the bush. They are a cheap board - but be aware, these are not Rolf KK boards, these are Hextronix boards, they are not cut very well, I just bought 3 and all of them the components are soldered offset to one another - eg, not one is identical. I was much happier with the official KK2.0 board - which can easily be identified by Rolfe's name on the back of the board. If they are made by the same mob, then please up your quality control!
Definitely a good upgrade from a KK2.0. stable flight straight out of the box the default settings. If you are a beginner it is worth while flashing it with the most current beginners firmware.
exelente tarjeta muy fcil de configurar y muy estable con el flash de simon k 1.12s biginer , la monte en un tricopter y funciona de mil maravillas y con el self level hago fpv bastante confiado
Absolute rock solid performance! I have this on a HK X550 frame, works superbly and so easy to use. Highly recommended for all experience levels. The back-lit display is a great bonus as well.
Good board, You NEED TO UPGRADE THE FIRMWARE! the stock 1.5 is not good! with steveis, and simonk escs, it is rock solid!
Great piece of kit for the money.
This is a wonderful controller up until the point you accidentally destroy it by trying to use the Voltage Monitor. The connector's polarity isn't mentioned on the topside where it would be seen, but on the backside which you will only ever see after you've blown up your board and removed it from your copter. The general convention for the polarity of connectors on flight controllers has been to have negative be towards the board's edge. This is not the case with the KK2.1. Be warned.

Otherwise I had excellent flights without even having to do any tuning (I was going to get to it eventually to make it perfect but I destroyed it before I could get to it).

After reading through forum posts (where quite a few suffered the same fate as me), I see some suggestions:
1) Don't bother with on-board Low Voltage Alarm, it's not very loud. Use an external one instead.
2) Only use a 1-wire lead for the positive only (do not send negative) or snip off negative board terminal.
The text would not show up on my KK 2.1 board, but Hobby King was awesome enough to give me a credit!! I'm very happy with customer service and I'm excited to try this board out once again.
got it today. Need to review my first KK2 version for tricopter. Thank you Hobby king
