Holybro KK Board, yet another KK clone

Holybro KK Board, yet another KK clone

Yo Bro! It’s the Holybro KK Multicopter Flight Controller, the latest version of the aging controller board design by Rolf “CapteinKUK” Bakke, featuring… the same old Murata gyros? The same “latest version 5.5” PCB that has been sold for well over a year now?

Look, the KK boards were the mainstay of the multicopter revolution, but in 2012 there’s simply no valid reason for getting one of these anymore. The “Bro” version sold at GoodLuckBuy is relatively cheap at $20 and comes in several pre-programmed versions for X, Y, Single-, Dual-, Hex-, etc. -copter… but why get this when you can get the better Eagle N6 / i86 for the same money? Not only is the i86 smaller and lets you select airframe type with simple DIP switches, but the STM 3D gyro is simply generations ahead of the aging Murata gyros on the KK board.

Hobbyking sells their KK board by pitching those gyros as being “high end” – but in fact the ENC type Murata gyros are not even being produced in volume anymore, they have been phased out back in 2008, and Hobbykings own HK401 helicopter gyro ditched the aging Murata ENC sensor for a new gyro sensor in 2011. It is said that these gyros are less vibration sensitive than SMD gyros, but we tested the i86 with props that were not quite balanced, and the SMD-gyro powered board still flew as stable as any gyro-only board.

MultiWii is perhaps one of the most well known Open Source multicopter projects. All its hardware and software is open source. Originally based on sensors taken from gutted Nintendo Wii controllers, this project has come a long way – and these days you don’t need to cannibalize a WiiMote or Nunchuk controller anymore. You get a board like the Crius in this review, and you’re set. But how well does it work and how difficult is it to set up? That’s what we’re looking into in this review.

Hobbyking released the i86 multirotor controller yesterday, and their stock of over 100 pieces sold out in less than 12 hours. The i86 appears to be a clone of the Eagle N6 V1 controller, though with a price of $19.99 – For comparison, Goodluckbuy sells this for $49

UPDATE 2 JUNE 2012: The i86 is in stock at Hobbyking again!

This controller uses a 3-axix MEMS gyro, and is thus in the same league as the KK controller due to the lack of a separate high-resolution accelerometer. How does it compare to the KK controller, and especially the current-generation controller boards with accelerometers? Read the review here on FPVCentral to find out more!

 

The big benefit of this product, aside from the price, is simplicity. There is only three gain potentiometers and a dip switch to select your type of aircraft (airplane, 2/3/4/5/6-Rotors)
