Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560) V2.0

Multiwii and Megapirate AIO Flight Controller w/FTDI  (ATmega 2560) V2.0
Multiwii and Megapirate AIO Flight Controller w/FTDI  (ATmega 2560) V2.0

This board features a multiple serial interface as well as a dedicated I2C interface. You can now plug in a GPS directly, and you still have extra ports for other external devices. In addition to that, the new ATmega 2560 has more IO pins so it can both read the PWM signal from your receiver and it has enough PWM outputs to control the ESCs directly without the need to do the PWM signal in software. 

This controller even has a MicroUSB port right on the board, no need to attach an extra FTDI USB interface.

The motion sensing side features a new generation MEMS Gyro, a MPU6050 by InvenSense, which has the MEMS Gyro / Accelerometer sensor on a single chip. There’s also a 3-axis magnetometer and a barometer sensor with a resolution of 0.01 millibar – approximately a 10 cm height difference.

Interested in GPS functionality? Well this is one of the most cost effective ways to get started - simply add a 10Hz GPS module (coming soon) and you’re good to go!

When is the 10hz GPS going to be available for this board?
 Z 46 points
don't wait. It's been more than 1 year now since they said they will push it out... 5Hz works just fine.
 tricopterY 865 points
Like many hypes and misinformation on the forums, the 10Hz GPS will not make much of an improvement in stability. Just bombarding the controller with data, that cannot be processed quick enough in time and reacted to. There is something like Control Loop Cycle time involved here, that is going to ignore the data, as it's got other things to do (or its own limitations/processing power etc). In control theory this is called the Frequency Response of the System, which determines the Resolution (how fine or co**** we can measure things and make effective use of them).

The HK scrubber does not like C o a r s e !! How interesting. It must mean something naughty to it.

Is ADC Vref 5v or 3v?
 tricopterY 865 points
The ADC VRef is programable via ADCMUX register, and you may use the internal voltages (eg 1.1V and 2.56V). But you would normally use Vcc i.e 5V.

Can i use HKPilot 2.5 Power Module with this board?
 tricopterY 865 points
No, You power this board either using one of your ESC's BEC, or get yourself an external SBEC that can supply 3Amps. There are two ways of powering this FC, one is through the Extend Power In header pins, that supplies the onboard 5V voltage regulator (some use this method if they are using a 2S/3S Lipo - direct connection, I would not connect a 3S lipo myself). The other way is the use of one ESC BEC or external SBEC connected to motor header pins - seamless.

This board name Crius V2 or deterrent?? in Arduino ,ArduCopter and multiwii only Crius V2 !!!
 tricopterY 865 points
In Multiwii you can either define this FC as 'MultiWiiMega' or 'CRIUS_AIO_PRO_V1'. Both work correctly, I myself always define it as MultiWiiMega. In Arducopter it's called 'CRIUS_V1'. Happy flying.

where do i get a replacement for the Molex 1.25mm 8Pin cable ?

Hi guys, have this board loaded firmware or need to load? How can read the firmware from board? Many thanks anybone
 v_max 2995 points
If I remember right Multiwii is preloaded.. but this almost senseless as it's basic configuration and you need to reconfigure it for your setup... So.. open files tab on this page and follow steps from manual you will find there... There are 2 manuals for MWI and for Megapirate, so you need to decide first which one you will try... MWI is simplier to start with... BTW ... you can download dump of binary hex preloaded firmware with USBASP programmer and AVRDUDE program... but this is sensless... it's binary data and has absolutely no value....
 tricopterY 865 points
This board comes preloaded with Multiwii version 2.2 (current version is 2.3) for Quad, in X configuration. But, you need to calibrate the Accelerometers and Magnetometers/Compass, using either MultiwiiConf or Win-GUI interface programs (all FCs need this step). Both programs are free to download from internet. Make sure you do not pull on the USB connector of these boards, as it may break off. Apply sparingly some epoxy to the legs to reinforce it Happy flying.

bought my third controller and i hope that i do not have to solder the vreg on this one a big plus for this board are the sensors they all work flawles i fly with 2 of the faulty????? boards that i have soldered the vreg and for sure i can say it is worth the money yes its not a crius but works the same for half the money AND PLEASE HK DO NOT I REPEAT DO NOT ERASE THE REVIEW AGAIN because that PISSIS the buyers off

Ahh, I can finally write a review on this product. I'm an original owner of the first version of this board, the one with a faulty GND trace. Upon receiving the board, I highly recommend you go over it with a fine comb. Aside from the known fault on the original board, I also had a lifted pin on the 2560 (A11) which resulted in intermittent yaw control. We're talking really really small pins here, unless you have expert-advanced soldering skills, and even if you do, it's probably best to just request a RMA and send it back. Now that's out of the way, on to the review. If you're new to the multirotor scene, this board is not for you. There's a lot going on with this board and to use it safely, you'll need to have a sound understanding of working/tweaking with firmware, how all the elements work and connect together, and the ability to troubleshoot/fly a buggy multirotor. If you've worked with Multiwii in the past and are looking to move on to something a little more advanced without busting your wallet, then this might be the board for you. It's ability to handle different flavors of firmware is what drew me to this board. As per the description, it can handle Multiwii, MegaPirateNG, and although it's not mentioned, I have been running ArducopterNG on it as well. It's worth noting that the MegaPirateNG and ArducopterNG are both ports of the Arducopter2 firmware. Bec

Opened up my FC today and wasnt really happy. I got someones returned board. HK didnt even take the time to remove all the the previous persons double sided tape from the back of the board. After reading all these reviews I am wondering if it is worth my time to figure out which version I have and dive in. Man those KK2 boards are making this thing look like a nightmare! All these features better be worth the time investment.

Top, no problems with it. I use it with Multiwii Software. Altitude hold, Level mode, mag, bluetooth, gps hold and return to home, all works fine with high precision. Nice Board... Altitude sensor must be covered with foam... Gps is a Locosys from a Tiny OSD 2 with serial interface, 10Hz and 112500 data transfer rate... You can use one gps modul for Flightcontroller and Osd (it needs only TX from Gps Modul)
