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.

I have a MultiWii PRO ver 2.3 which I'm having trouble getting to talk to my Win 8.1 PC (64bit). I found this exchange between Trevor and Moochasas here (my problem seemed to be similar): "Hi Trev, yes you need the drivers for the board. what you are looking for is CP210x_VCP_windows..." [downloaded that] and this: " "In the purple file section above check out the 6th file down and the 2nd last on the page [did that]..... there is also a great vid on line showing everything you need to know" I downloaded and installed the exe file in CP210x_VCP_windows v6.7, but the response I get when I try to run CP210xVCPInstaller_x64.exe is that the "device driver wizard was unable to find any drivers designed for your machine" and the installation will not complete. I have gotten a lot of help here so far, can anyone tell me what I am missing. Thanks, Paul
Word of caution ...roll your own sketch ... meaning download from source repository , uncomment the needed lines, check compile and upload (clear EEPROM first). AP_Mode error is not common and should not show up if the proper GPS lines in config.h are uncommented. Please remind us of the GPS unit you are using and the lines in the GPS section you uncommented.
Use MWC 2.3 or 2.2 official for now. Download from Multiwii source. Uncomment your frame, uncomment the sensor. For Ublox GPS uncomment, a) Ublox, b) Serial 2, c) Baud Rate 38400. Clear EEPROM before uploading. Uncomment motor_stop so your motors do not spin on arm ...
see this sketch for me: www.link AP FlightMode ********************************** /
* * * * / * Temporarily Disables GPS_HOLD_MODE to be able to make it possible to adjust the position Hold-When moving the sticks. * /
* * * * // # define AP_MODE 40 // Create a deadspan for GPS.
I have to enable or disable AP_MODE?
Individual sensor control allows the flexibility of enabling discreet modes with or without the influence of others. Say you want to take 360 deg panoramic video sweeps. a) Hover then increase height - no flight modes enabled initially.b) enable Position hold to stay in one place c) enable Alt-hold to stay at the same height d) Enable mag hold so you can turn 360 degrees. After you are done, you want to descend and keep making 360 videos ... but still keep your position so avoid drift. 1) You turn off alt-hold to go down, 2) keep mag hold and keep turning in one spot. 3) When nearing the ground enable alt-hold again, with PH and Mag enabled for a last 360 degree video pan. Then land.
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
