MultiWii 328P Flight Controller w/FTDI & DSM2 Port
The MultiWii 328P is a gyro/accelerometer based flight controller that is loaded with features. This version of the MultiWii supports DSM2 satellite receiver 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.
Features: • SMD component design with Atmega328P • ITG3205 Triple Axis Gyro • BMA180 Accelerometer • BMP085 Barometer • HMC5883L Magnetometer • Servo output for camera pitch and roll control • Separate 3.3v regulated power supply for the sensors • On board logic level converter
Specs: Dimensions 50x50x12mm Mounting: Standard Mk style mounting holes 45mm X 45mm Weight: 13.9g
I have downloaded the MultiWii_2_2_hk328p file from the file section here. I have also downloaded the Ardunio software. I have gone the the config.h section and have checked the define.h section and confirmed the file is set up as an xcopter for this board. I am using the built in usb port and J1 is to the bottom if you are looking at the board with the direction arrow at the top. I have confirmed that I am using com5 in my device manager.
Do I select the Arduino Uno board? and ARV ISP programmer? The error I am getting is:
avrdude: stk500_getsync(): not in sync: resp=0x00
After I get it programmed what is the motor layout for d9,d10,d3, and d11?
tricopterY... thanks for answer. went yesterday outside for a trial with my tri and crashed. The frame was to weeny, broke in half....have to build another one and much stronger :) this was my first tricopter done in my life, so...any way.... I am bad pilot..lol.....Thanks
To begin with your tail-motor should not tilt to the left when viewed from rear (0.27s on video). Make sure you have defined YAW_DIRECTION -1 in the config.h file. If you are using all CCW rotation props, you must setup your tail motor to about 10 - 15 degrees to the Right when viewed from rear. This is to compensate for the torque generated by the CCW spinning props. If you opt to use CW prop on the front right motor, you can reduce that to 5 - 10 degrees. This is just a guide and you may have to adjust it to suit your prop and motor bell size. Your frame also looks too weeny and can easily flex, glue some stiffening ribs to beef it up. Also, make sure you have nicely calibrated your Accelerometers and Magnetometers. Slight variation in static/stored values vs sensed ones causes correction and that leads to oscillation. A high gain value on your Yaw PID can also cause oscillation.
Helo all,Im bought this board and have problem with servo oscillation with my small 300 mm tricopter.This is a vid YT link showing what going on:
2 thumbs up!
This is a very powerful board for little money.
I ended up buying this because the KK2.0 was on back-order and I have not regretted that one second.
Yes there is a higher starting threshold then the KK2.0 which is more or less plug and fly but it's worth it.
I have uploaded a file for this card here on HK that collects all information i could find about the card. There are some things you should know before you start connecting things and uploading a new MultiWii firmware.
First the markings on this board is not 100pcnt correct.
AX2, AX3, AX4 is not AUX 2,3,4.
BAT is not VBAT, LCD and PWR are not correct either.
You can see all this on my picture under files.
So with this knowledge we can start the review.
1.) Value ****
You get great value for your money, Accelerometer, Gyro, Barometer, Magnetometer and a nice I2C port to which you can connect a I2C bridge and a GPS and get Alt Hold and return to home. You also get an easy card to upgrade thanks to the USB port.
It is easy to add an Bluetooth module to this card without soldering (connects to AX2, AX3). This will give you easy access to your PID settings and other neat stuff on your android phone or tablet. Well worth the 5-8 usd extra cost.
2.) Quality ***
Yes there are mistakes on this board but these are not anything that will make it a deal breaker. It's more of an inconvenience.
First the markings on the board is a l
so far so good, pretty stable, any problems i encountered were all software based. usb port is mini usb (not micro usb) and pretty solid unlike my other board. seems much more value for money compared to the kk2. will need to solder your own pins if u want to add on the bluetooth module though for on the fly adjusting of pid settings
It is cheap, open source and very reliable flight controller board with good quality sensors. It gives you a lot of freedom of configuring your multirotor. But barometer sensor is unusable. But for this price this is best buy.
strong controller buy it from Egypt or Medal East Egyptuino.com Online store

This is one of the best boards hobby king has to offer, It has awesome quality of soldering and reasonably good sensors which can provide great flight quality, the onboard FTDI chip is a plus...although the USB port socket should have through holes to make sure that users don't accidentally rip off the usb socket while disconnecting the usb cable...I dont understand why people don't buy this instead of the KK2...it has more sensors and can offer more flight modes...overall the best board which you can buy for the money...
