I bought mine from them - they are just Good Luck Buy on ebay as far as i know.

These boards seem to work pretty well - I'm using one with my MultiWii PARIS board without any problems - but they seem quite expensive to me. You can buy a flight controller for not much more that contains all these sensors as well as everything else. I guess if you want to play around with the sensors separately you end up paying more 

Also I'm not 100% sure if the barometer in the 10 degree of freedom board is as accurate as the new 'high precision' version that you get with the latest rabbits etc. - it seems to keep my quadcopter to the nearest meter or two but I've not tuned the PIDs yet.

I think the main advantage of these separate sensor boards is that you can mount them on the flight control board with some vibration damping foam or gel to help isolate the sensors from vibrations, which you can't do with built in sensors. I've not seen a proper test done to see how much of a difference this really makes though.

I agree and was going to say the rctimer board in another thread on here looks much better value and it comes with the atmega2560 mcu, I suppose if you already have a atmega board like the flyduino's then this is a good buy 

[Gaza07]

Yes your both right it wouldn't make sense to buy this if you didn't already have a board to fit it to,
but I have a couple of flyduino 2560 boards that would benefit from such as this 

[MadMax]

I see what you mean now in the case of already having the mcu separate it is a good deal and I suppose with things being separate you could always upgrade again later if needed 

[Gaza07]

Ive just ordered one of these, it will be fitted to my Flyduino setup

Looks identical to mine and a similar (possibly slightly better) price as well.

I've noticed that some of these come as 3-5 volts and some just say 3 volts - worth checking for anyone buying one.

I think the 3.3 volt only ones are the 'ultra small' ones.

[Gaza07]

Phew I got worried then because I didnt check but it says its 3-5v  I have noticed the prices of these 10 dof boards have been dropping they were over 30 quid a few weeks ago

In your first link they are £29.30 so you saved just under £4.00, it makes you wonder what the real cost of these sensors are if they are making a profit even after posting it half way around the world, look forward to seeing your report
