APM 2.5 and GPS/Compass module

I recently purchased this from eBay: search.ebay.com/111019583257 and on the board itself for the GPS there is no arrow pointing forward. Does it matter which way it’s pointing? I believe it’s an APM 2.6 because near the bottom of the description it says what’s in the packet and it states 2.6 arducopter. What’s the best way to verify? I am kinda new to all this.

Just curious.


Hi Brad,

You should contact your seller, the board from the link is a clone.

In the original APM the forward is pointing to the inputs.

The APM 2.5 have a on board mag built in.
