hi, can someone please help me, i cant get my board to arm. i have callibrated everything through the software and have tried yaw full right thr down but will not arm. also have made sure yaw/thr are not reversed and in the software my yaw right goes over 1900.
any help would be much appreciated.
This board does support GPS. Any I2C gps will work. Do not use a standard serial gps as the Atmega328P is not powerful and you want to off load the processing of the gps. There are I2C gps on HK just do a search. I use the I2C GPS from Flytron the Navigatron v2 - I2C GPS for MultiWii. The GPS will be more than the cost of this board but will do GPS hold and return to home.
You program the board so you can use one of your aux channels to switch heading hold on. You can have up to two aux channels connected. You can also have low, mid and high (three position switch) on each aux channel.
Thanks for the reply I just realized I made a typo in the original post and meant to say I will not be using rc and want a switch connected to the board to turn on heading hold. What I want to do is use heading hold to steer a boat in a straight line with magnetometer and gps. I want to point the boat in the desired direction turn on a switch to get heading lock and launch the boat. Is it possible to wire a switch directly to the multiwii board.
The code will need modification but is possible. Biggest thing is finding a way to arm the board without RX input. You can have it in heading hold mode on arm. You can program it to airplane mode and would just need the rudder servo output connected for steering.
You will need to change the code. Two possible ways I can see is change the arm sequence from stick input to a hard switch, or change the mode the controller goes into when in safe mode. As there will be no Rx connected the board can be set to go into safe mode. In both instances programming will be needed. I would have a separate switch to start the boat motor so you check that the heading hold works each time before sending it off.
I use the I2C module from flytronthe Navigatron v2 - I2C GPS for MultiWii
3 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...
