Which GPS to buy for a Crius AIOP v2 board?
Which GPS to buy for a Crius AIOP v2 board?
I've always used the CN-06 V2 GPS for previous builds, but I haven't built for a while, and that gps seems outdated. I see a number of options, but its hard to tell which are compatible with multiwii or which is best.
Examples I'm finding in the $17-$25 range are
UBLOX NEO-M8N (this appears to be the newest and most full featured, but is it compatible?)
Crius U-blox NEO-6 V3.1
Crius U-blox NEO-6M V3.1 (possibly the same as above)
Ublox NEO 7M
Also, even of those listed, sometimes the same models are picture a little different, or often have the antenna hanging off rather than attached to the board.
I'm not too picky, I just want something to plug and play with minimal headache, like how the CN-06 V2 was.
Any recommendations?

They're all compatible. On the software side of things, there's no real difference in data from any of the neo modules.
Re: Which GPS to buy for a Crius AIOP v2 board?
Thanks for the reply. I was looking at the NEO-M8N, since from the limited info I could find, it seems to be better. However I noticed it has 6 wires instead of the usual 4. Can anyone comment if this will work, and if so how to hook it up?
I've been scouring the web but I cannot find a pinout/schematic, nor could I find a single instance of anyone using it with multiwii or an aiop board. Unsure why this info seems so hard to find.

Post a link to the GPS module from which you are talking about. That would help.
If it has 6 wires then it probably has a MAG on-board.

Here is an example link

From what I can gather, this one is newer and might be more accurate, and I believe can use GPS and Glonass simultaneously. But can't say for sure. Info seems very scarce.
I don't want to be a guinea pig, I just want to get the best performing GPS i can for under $25

Re: Which GPS to buy for a Crius AIOP v2 board?
Just as I thought. Even says it in the description that is has an on-board MAG "BeStar BN-880 Ublox NEO-M8N GPS Module w/HMC5883L"
You are correct that GPS and Glonass can be run simultaneously.
Connecting it to the Crius AIO Pro board should be easy.
Post back here when you have the GPS with more detailed pictures.

Due to http://www.csgshop.com/product.php?id_product=173 and http://www.drotek.fr/shop/en/home/512-ublox-neo-m8-gps-hmc5983-compass.html there is also an I2C interface. However, I haven't found any detailed description as to it.mxmaniac wrote:However I noticed it has 6 wires instead of the usual 4.
I assume that the gps is transferred via Rx/Tx and the compass via I2C.
Due to the datasheet http://www.u-blox.com/images/downloads/Product_Docs/u-bloxM8_ReceiverDescriptionProtocolSpec_%28UBX-13003221%29_Public.pdf the Neo8 appears to be compatible to the Neo6.

Correct on both accounts.
That BeStar GPS will have horrible compass offsets, however. Sticking the compass under a (magnetic!) metal shield is as close to disabling proper functionality as it gets.

It this your experience or assumption?Arakon wrote:That BeStar GPS will have horrible compass offsets, however.
The metal shield could be made of paramagnetic (=not magnetic) metals like aluminium/aluminum.Arakon wrote:Sticking the compass under a (magnetic!) metal shield is as close to disabling proper functionality as it gets.
Re: Which GPS to buy for a Crius AIOP v2 board?
Experience from another forum, where someone bought it for his APM and does have horrible offsets.
The metal shield is magnetic.

Re: Which GPS to buy for a Crius AIOP v2 board?
That'a a pity, indeed. The approach to combine GPS and compass and to set them on the top of the copter far away from the motor wiring disturbing the compass as well, is promising. But, in this case there is obviously no benefit. Thus, you still have to use your own compass, the second one seems to be unneccessary.
