The amount of information out there is daunting, especially considering the number of configurations out there possible.

I have included references to other blogs that really helped me out with some definitive information that I needed.

For example, it took me forever to find something that said UART2 is Pin 3 and 4 only after GPS is enabled.

This may have been obvious to some people, but for me it was elusive and very frustrating when trying to visualize the layout of the board.

Here are some from Amazon (yes, there are endless choices from other vendors).

It works at a higher rate, but steals clock cycles from the CPU that you need for flying ).

I was wrong since Im running a 250 quad, so this is heavy and takes a lot of space.

Its better to get a mounting post that is more like this (there are different flavors of the chassis mount, but you get the idea).

You should open up the unit the make sure youre using the right wires.

Also, the mount kit is aluminum, so it would shield it further.

One is soley used for GPS via pins 34 (uart2)(this can be remapped but not suggested) and USB,BT,frsky telem and osd on UART1.

Cleanflight Baro Mode Serial On A

Or Use a soft serial on a spare pin pair (assumes using ppm) and route MSP to that port.

ANGLE would probably be the better of the two as it is more stable you dont really want the multi-rotor performing acro loops on its return home.

If you do not include the three features then the GPS mode you select will behave erratically at best, dangerously at worst (fly away).

How quickly it does so depends on the specific GPS unit you have.

Others will cold start each time you apply power to the aircraft.

So, if you do not allow a 3D lock then there is a fair chance that the FC will record home as some random place on planet earth.

In such a case switching to GPSHOME will probably be the last you see of your multi-rotor You have been warned.

I love naze32 for my 250 but I love my iris for everything else.
