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.

How is this control board powered? Is it supposed to be powered from the escs coming into the board? My escs do not have becs in them for power out. If this is the case does this mean i have to get a bec and connect it to the board? What size bec would i need (volts,Amps)? Also at what positing would the power in to the board need to be connected?
Hi Wom .. you mean servo gimbal support? It is okay with MWC 2.2 but very confusing with MWC 2.3. Look at the first posted doc to uncomment (servo_tilt) I think. The plug in your two servos to the designated pinouts ... MWC 2.2 allows you to make servo adjustments in config.h ... MWC 2.3 is via GUI but lacks documentation ... If you want/need gimbals, go for the brushless gimbals ... that need a separate controller ... pricier but beterrer.
Using sonar alt-hold is interesting ... I did not change throttle position so the altitude did not change ... except the copter was moving forward on itself because I added the camera and it tilted forward ... was lazy to rebalance as I thought I could compensate ... but it kept moving faster forward even without any input ... should not been ... oh well. Four "new" props and I'm ready for another go ...
Just finished building my diversity controller so my 2 little RC305's can fight out which signal strength is the best.... 2 antennas (clover leaf and a helical directional)........ so hopefully the best of both worlds..... a FF (fellow flyer) is coming up on sunday to fly his Cinitank which has the new Revo CC3D board...... $140..... woohoo....... and James is bringing a newby who has just got a 250 together and has never flown it.......... Hope its good weather...... pictures at 11.
Mooch .. I feel like a one year old just learning to walk ... I have in my head what it would take to fly this thing ... but matching the head to reality is a different game. Thanks for the tips ... hope you gave a galloping time at the field.
Welcome to the untold world of FPV.. what you see isnt what you get..... and yes its like learning to walk (or fly) all over again.... but the great news is that the curve is not steep as you already have the skills required..... you just have to do it differently and that is the part that NO ONE talks about.... even greater news...... one of the FF's has an FPV wing that he is bring up and also a (get this) jet propelled wing...... that hasnt flown yet..... I feel like a 10yr old days before chrissy..... and mind you its 400 degrees C here at the moment so unlike you NH people our chrissys are anything but white......
Can a 4 pin connector be connected to the serial port 1 on the multiwii pro since the gps is on serial port 2 and this work through serial port 1? Can serial ports just be soldered on with pin connectors like here?:
In the Arduino software do i have to enable the serial port after adding the 4 pin connector for the MinimOSD like you do for the GPS? Or after to connect the MinimOSD everything is ready to go and there is nothing you need to change?
I should add ... a brand new MininOSD will not work properly unless the MWC friendly firmware and fonts uploaded. Best to get the latest Minim board (V2 I think) that has Vbat and RSSI pins preinstalled.
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
