Let me start off with a quick pre-summary: This board is an absolutely horrible piece of hardware.
I bought this thinking that I could get the reliability of a kk2.1 in a smaller form factor. Boy was I wrong.

The first quad I built is driven by a kk2.1 board. It took minimal time to set up, and flashing with Steveis allowed that little FC to control my quad as if it were on rails.

As for the nano multiwii board here, I can't even come close to saying the same thing. It drifts all over the place, PID tuning is near impossible, as none of the changes actually make any difference, it has a terrible response to stick position, especially with throttle. It suffers from, what I found on forums around the web to be called the "yo-yo" effect. Throttle will violently increase, and any attempt to compensate causes it to fall out of the sky.
But hey, At least it powers on, right?

I could continue, for quite some time, but I'm probably about to run out of text space.
So, Final summary... If you're looking for something reliable, go with the kk2.1 instead. It's not worth the waste of money to prototype the this mw board.

A real Pain to setup and connect and bad documentation. Once you get it to connect then maybe its ok but after getting a new PC and after spending 3hr trying to connect I ripped it out of my tricopter and just about tossed it in the garbage.
I so miss my original KK2.0:(

Good board. Simple, cheap and with good sensor. Ability to use on 2s without external BEC is nice as well.
As for flight and handling 0 it's just multiwii. Depends on setup and modifications, but I dare say that it's the best software for small and aerobatic copters around.
I've uploaded the picture of ISP connections. Programming via USB can be tricky sometimes because of your computer's drivers. But ISP programming always works flawlessly.
Recommended.

P.S. Having it supplied with pins unsoldered would be perfect.

I have this flight control on a 360mm quadcopter and it works very well. I am using the Bradwii firmware which has autotune. The only issue I had was missing the serial usb config line which then messed up the usb connection but I was able to reprogram using another arduino uno. Once I had the config.h set correctly the usb connection worked great with bradwii. This not the fault of the nanowii, it was my lack of experience. This flight controller works well and is very lightweight.

Nice board, really well suited to the 250FPV. You will have to do some research online to get it running but well worth it.

Sorry to say but this board or the Ardunio software it uses needs some work.
I have not been able to get Ardunio to upload new code through the USB port after may hours of trying. Tried different cables, ports, revision of software, manual reset of board and no go. It always hangs during the upload process
There is lot of NET discussion about problems with the Arduino Leonardo processor and this boards seems to suffer as well.
Really too bad as the price is good and it should do exactly what I want but if one can not download code, a Arduino Leonardo based board is no use at all.
Will steer clear of Arduino Leonardo based boards from now on.

Great small Controller. Have 2 of them in use. If you want to use a Bluetooth module, you have to remove (break off) the white connector and unsolder the remaining pins. To mount them I used Gyro / Flight Controller Mounting Pads, also available at HK.

For $20, its an amazing board! No where near a CC3D, but then again, a CC3D is about 3X pricier. My only gripe about this board is the lack of mounting holes, so no way to hard mount this board to anything.

This is a great Fc board pretty easy to set up requires some small PID adjustments but once to get it tuned this board is extremely stable and it will also do flips very well. the only board i would rather have is the naze32 . if it had a barometer it might be better because it likes to change altitude randomly but its completely manageable. i have seen this board out perform APM, Hoverfly and other multiwii boards.
