The MultiWii PRO is a gyro/accelerometer based flight controller that is loaded with features. This version of the MultiWii supports direct connection of a GPS module (package includes MTK 3329 GPS module) allowing for ultra-precise positioning functionality. With expandability options and full programmability, this device can control just about any type of aircraft. This is the ideal flight controller for your multi-rotor aircraft.

If you have never used Multwii, go with MWC 2.2 for now. It is not as complex as MWC 2.3 ... just getting to the config.h of MWC 2.3 can be a challenge ... let alone the configuration. There are also the MWC 2.3 Nav beta versions ... do not touch those yet. You will find the MWC 2.2 multiwii configurator along with the zipped download package for MWC 2.2.
Thanks for the reply and advice, I'll probably just stick with 2.3 only because it seems like more sketches and discussions are in line with that. I've done some exploring in the config h and with me using a MAC and OSX, 2.3 is more Compatible.
If you install MWC 2.2, there is a Mac version of the GUI included in the download. If you want to go deeper into the hobby might want to get a MS machine as MWC 2.3 Nav will only support windows for now.
I've seen several discussions and videos where they say when setting up your gps for the first time to only define the mtk intialize, and to leave the NMEA undefined. Then go back in after you compile and upload, undefine the mtk intialize and define NMEA. Also saw where using a 57600 baud vs the 115200 will give you better accuracy? Any feedback on this before I set up my new board? Thanks in advance.
By the way I too am new to multiwii I have a kk2.1.5 on my first quad, and wanted to explore a more advanced world!
Assume you have the MKT 3329. GPS to uncomment a) NMEA,b) Serial 2 c) Baud rate 115200 and d) Init_MKT. Set Serial 2 to 115200. Use MWC 2.2 official for now - use WInGUI 2,.2 for the firmware. Google and download. Watch Mooch's how-to vid ... closely, do not assume anything. You have the MKT okay?
Hello to everyone.
Recently I bought a Multiwii pro board from HK. After I did as much research on the internet as I could I decided to change the magnetic declination on the program or sketch as it is called. I downloaded the file called " MultiWiidev_with_nmea " from HK and the Arduino 1.0.6 with the driver. I changed the sketch compiled it and uploaded it to the board. When I run The GUI application and tried to connect, I got the following message
" Flight control sw version mismatch: Expected:230 Got:211 ", and a red led kept blinking as well as a green one. So could someone help me here. It will be appreciated
Needless to say that I am new to this.
Also is this sketch the one the board came with?
I thank you in advance.
PS. I have a feeling that many questions will follow
Your first error means you uploaded MWC 2.3 but are using the MWC 2.1 GUI - use the proper GUI for the firmware you are uploading. With MWC 2.2, the LED's will keep blinking until you calibrate the sensors in the GUI. To get the GPS working (assuming you have the MKT unit) uncomment a) NMEA b) Serial 2, c) Baud rate 115200 (make sure the serial 2 GPS is set to 115200) and d) Init_MKT ... sometimes the last line is not needed results vary - but for now use this. The default mag dec is for Hungary - change that for your location.
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
