KK2.0 flight controller board has been out of stock for a while now. Many say it’s been so popular Hobbyking simply can’t keep up with the demand. But is it really? In the last few months some of us have noticed there is a new product available in their store, namely the KK2 status LED designed by MultiRotorMadman.
The LED is nothing new, but the KK2 board in the sample picture seems to be nothing like what we have seen before. Would that be the new KK2 board!? I guess there might be a new KK board that is about to be released!
Why do I say that?
From the technical side of view, on the KK2.0 board the output pins for the buzzer are in the top right hand corner, not the top left corner as shown in this picture. On either board it is connected to the Piezo buzzer output pins which is on the right side of the KK2.0 board (left pin is negative/black wire, right pin is positive/red wire). Also notice the different chip right in the top middle of the board in the picture. In the KK2.0 there are only two chips, one is gyro sensor and the other is the accelerometer. I think in the new version, they might be using a single chip that contains both sensors.
From the sales side of view, like the KK2.0 flight controller board, it’s been so popular, the same thing is going to happen to the new version of KK2 (KK2.1?), so it would make sense to think HK is stocking up this controller for its release?
It’s all just guessing at the moment! But wouldn’t that be cool if the KK2.1 is really on its way? :-D
UPDATE (01/Dec/2013) : I was right!
So my guess proven to be correct, Hobbyking has released the KK2.1 on the 28th of November. You can buy it from this link:
Hurry up if you want one, they tend to go out of stock very quickly, and you might have to wait for weeks to get new stock.
To Udpate the firmware on the KK2.1 using Arduino, you can follow these instructions.
Quoted from the HK website about the new KK flight controller:
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.
