ZMR MWC MultiWii Lite Flight Control Board

Nothing new really, plenty of boards exactly like this one. But I bought one, and figured it deserved it's own thread so that if someone else searches like I did, at least this could be a starting point for the info on it, as it does not come with any instructions, and searches do not really come up with anything. This thread could also be used for the SE version which they just started selling from myrcmart.com. So far my dealings with myrcmart has been great, and the shipping was very fast. I received my goods in less than a week, unlike some other venders that take 3weeks +

MultiWii Lite lightweight version supports the following aircraft models:
GIMBAL -------- PTZ Stabilizer Independent (non-flight control purposes)
BICOPTER ------ 2-Axis Aircraft Avatar
Tricopter ----- Y3 (Y-Type 3-Axis)
QUADP --------- 4-Axis + Classic Mode
QUADX --------- 4-Axis Mode
Y4 ------------ Y-Type Four-Axis
Y6 ------------ Y-Type 6-Axis
HEX6 ---------- 6 Axis + Mode
HEX6X --------- 6-Axis x Mode
FLYING WING --- flying wing with a (non-multi-axis machine, the program is in testing phase).
Tool to connect the computer via FTDI, flight mode can be easily converted at any time.

MWC MultiWii Lite lightweight version of the hardware configuration:
ATMEGA328P microcontroller
ITG3205 three-axis digital gyroscope
ADXL345 three-axis acceleration sensor

Dimensions 50*50mm
Standard MK Style Mounting Holes: 45*45mm
Weigh: 13.5g
SMD component design with atmega328P
ITG3205 TRIPLE AXIS GYRO, ADXL345 ACCELEROMETER
Design with servo output for Camera Pitch and Roll
Separate 3.3v regulated supply for the sensors
On board logic level converter
All the out puts are labelled for easy identification

Was a nice touch that it came with some jumpers.

I also bought:

I've seen the same board on goodluckbuy with a different name go for $40, so I think this is a good deal for what it is.

Here is a good thread on similar boards:
http://www.rcgroups.com/forums/showt...+control+board

So basically I tried to upload multiwii 2.2 ( multiwii.com) and I seemed to run into a problem. Not sure if it was something I did or not, but after a few days of searching and reading, I discovered the bootloader was corrupted. So I used my USBasp programmer to upload the bootloader with audrino 1.0.5 You can get one here also:
http://www.myrcmart.com/rcx-usbasp-p...er-p-6216.html

Also here is a good link to learning more about microcontrollers:
http://www.ladyada.net/learn/avr/whatisit.html

After loading the bootloader, I just defined CRIUS LITE in the config.h and my QuadX, and got everything to work fine.



I flew it in the house, but it's raining out so when it stops I will get some video up. BTW ZMR also makes that frame, which is the same as the HK PCB 235.

That's a nice TX I just have a turnigy 9x V2 and have no idea how to set it up for a quadcopter with this board! I just ordered the ZMR X Power quad from Myrcmart(it was the only one not sold out the ARF kit) hopefully by the time it arrives I will have somehow solved this problem or found someone who is flying this FC with the Turnigy or Flysky TX.

Just use airplane mode then set your endpoints in the gui.

Yes that is what you do with a quad. Once your quad is built, you hook the flight controller to the GUI. Then with everything powered up, and props off, you adjust the endpoints on your transmitter and watch the bars in the GUI so that they go from 1000-2000 and 1500 is the mid point.

can you guide me I just received my ZMR and am having trouble with the Multiwii board. I checked all my escs and motors on the throttle channel of my turnigy rx and they all work however when I connected everything to the board nothing is working only 2 red leds flash and keep on lit and a blue one flashe on for some seconds and then goes off!! I tried to download both from Multiwii and Arduino to maybe try setting it up through the GUI but failed miserably as I am getting stuck somewhere each time!!

Well I can help but I won't re-write the whole process as there are plenty of guides out there. You can try youtube for some tutorials also. Other wise you have to write all the steps you've taken and where you are getting stuck. The more details you give the easier it is for someone to help.

Hello it's me again I have managed to get the thing to fly however I find the yaw effect too tame it really goes slow when you try piros with it!! And also I noticed that sometimes it has a tendency to piro slowly to the left but on rare occasions!!

What did you need to do to get this working? Your experience will be helpful for others reading this thread.

What tuning have you done on the MultiWii? What are the current PID settings?

At the moment I am trying again to upload the arduino sketch as explained in the Myrcmart tutorial however when I tried to upload the settings to the fc it stopped because it is saying GETESTIMATEALTITUDE was not declared in this scope!!! I can't get the Arduino sketch flashed to the board!
